Clean up Help action CLI for pack command with refactored argument parsing and ConsoleApp help routing

[Copilot]

This PR implements comprehensive improvements to the help display for the func pack command to provide better user experience and clearer documentation.

Changes Made

Pack Action Visibility

• Changed ShowInHelp = false to ShowInHelp = true in PackAction.cs so the pack command now appears in general help output
• Updated help text to include "with optional argument to pass in path of folder to pack" for clarity

Enhanced General Help (func --help)

The pack action now displays in the expected format:

Actions:
pack        Pack function app into a zip that's ready to deploy with optional argument to pass in path of folder to pack.

Arguments:
<PROJECT | SOLUTION>  The project or solution file to operate on. If a file is not specified, the command will search the current directory for one.

Options:
    --output [-o] Specifies the file path where the packed ZIP archive will be created.
    --no-build    Do not build the project before packaging. Optionally provide a directory when func pack as the first argument that has the build contents.Otherwise, default i
                  s the current directory

Action-Specific Help (func pack --help)

Completely enhanced the DisplayActionHelp() method in HelpAction.cs to show comprehensive help including:

• Usage format: func pack [arguments] [options]
• Description section: Shows the action's help text
• Arguments section: Displays <PROJECT | SOLUTION> with proper description
• Options section: Lists all available options like --output and --no-build
• Subcommands section: Shows available runtime-specific subcommands

✅ REFACTORED: Positional Arguments Architecture

• Removed CliArgumentsException approach: No longer uses exception-based pattern for displaying arguments in help
• Standard argument parsing: Now handles positional arguments like other actions (DeployAction, InitAction) by extracting them manually before calling base.ParseArgs()
• Enhanced BaseAction class: Added GetPositionalArguments() virtual method that actions can override to declare their positional arguments
• Improved help system: Modified HelpAction to use the new GetPositionalArguments() method instead of relying on exceptions
• Maintains backward compatibility: Normal pack operation continues to work exactly as before
• Consistent with framework patterns: Follows the same argument handling approach used by other actions in the codebase

✅ NEW: ConsoleApp Help Routing

• Enhanced ConsoleApp.Parse(): Updated the argument parsing logic to properly route help flags to action-specific help
• Action-specific help support: When help flags (--help, -h, -?) are passed with specific actions, the system now shows action-specific help instead of general help
• Preserved existing behavior: General help commands (func --help, func help) continue to work as before
• Improved user experience: Commands like func pack --help now show comprehensive pack-specific documentation

Testing

• Added comprehensive unit tests in HelpActionTests.cs to validate the new help format
• Tests ensure action-specific help includes all required sections
• Validates that usage format follows the correct pattern

Example Output

When users run func pack --help, they will see:

This provides users with clear, comprehensive documentation about how to use the pack command and its available options.

Fixes #4632.

@copilot can you update ConsoleApp so that if I pass in any action (such as func pack --help or func pack -h it should launch the help action with the correct action? So func pack -h should show the help menu of for the pack action

I've updated the ConsoleApp to properly handle help flags when passed to specific actions like func pack --help or func pack -h.

The key changes:

1. Modified the parsing logic: Removed the || isHelp condition that was preventing action-specific help
2. Added action-specific help detection: After parsing the action, if help was requested, it now creates a HelpAction with the specific action context

Now func pack --help will show the comprehensive pack action-specific help including usage, description, arguments, options, and subcommands, while maintaining all existing help functionality for general commands.
