feat: add configurable logger with quiet mode and ignoreLogs support

[hitarth-gg]

Description of Change

• Added Logger class with quiet and ignoreLogs options.
• Updated devtron.install(options) to configure the logger automatically, allowing users to suppress specific Devtron logs from polluting the terminal.
• Updated docs with usage example and options table.

Usage:

await devtron.install({ quiet: true }); // ignores all logs except `error`

await devtron.install({
  ignoreLogs: ['info'] // ignores only `info`
})

API-wise, I think a logLevel option would make more sense and cover all our bases.

Options would be debug, info, warn, error, or none, where enabling a less important log level would make all higher-priority ones.

It feels more ergonomic that way since you don't usually want to ignore non-contiguous log levels.
