Command-line improvements

Feature description

act works beautifully, but only after I tried and found out all necessary params, the result looks quite complicated 😄

act --container-architecture linux/amd64 -P ubuntu-latest=-self-hosted -W .github/workflows/ci.yml -j build

I suggest the following improvements:

• As long as there are no multi-architecture runners, act can determine if not running on amd64 and set --container-architecture linux/amd64 if necessary
• A new flag --self-hosted replaces all runs-on by -self-hosted (instead of needing to replace all of them manually like macos-13, ubuntu-22.04, ...)
• The -W ci option could just check if a file for the value exists (.github/workflows/ci.yml or .github/workflows/ci.yaml)
• The -j option could prompt interactively with a multi-select if no value was passed and more than one job exists in the workflow, otherwise just run the single job without prompting (no error for a missing value displayed)
• A new --skip publish,release option to only run build and test jobs for example (if -W would be implemented, it could skip workflows too)
