📖 Enhance README with comprehensive examples and improved workflows

[Copilot]

• Analyze current repository structure and understand the action
• Review existing examples in README.md
• Run tests to ensure repository is in working state
• Identify areas where examples need to be more descriptive
• Create more comprehensive workflow examples for different use cases
• Enhance the allow list file example with better descriptions
• Add real-world scenarios and use cases
• Update the documentation to be more helpful for users
• Test all changes and ensure they don't break existing functionality
• Address code review feedback about token documentation
• Final formatting and testing completed
• Remove Advanced Use Cases section per @stoe feedback
• Update organization workflow to use matrix strategy and read org names from filenames
• Simplify Allow List File Examples section (removed confusing detailed examples)
• Add documentation links for immutable releases and enterprise policies
• Remove incorrect fine-grained token guidance for enterprise settings
• Fix JSON escaping in shell script for matrix generation

Latest Changes

Shell Script Syntax Fix:

• Fixed JSON escaping in the matrix generation shell script
• Line 96: Changed MATRIX_JSON="{"include":[" to MATRIX_JSON="{\"include\":["
• Line 108: Changed MATRIX_JSON="$MATRIX_JSON{"org":"$ORG_NAME","file":"$file"}" to MATRIX_JSON="$MATRIX_JSON{\"org\":\"$ORG_NAME\",\"file\":\"$file\"}"
• Ensured proper JSON syntax throughout the shell script for GitHub Actions matrix generation

The shell script now correctly generates valid JSON for the matrix strategy, preventing potential parsing errors in GitHub Actions workflows.

@copilot, no need for "Advanced Use Cases"

@copilot, no need for "Advanced Use Cases"

Removed the "Advanced Use Cases" section as requested. The README now flows directly from Security Considerations to Allow List File Examples. Commit: 455dfeb

Hmm - don't know if I love the examples Copilot is generating :')

As additional examples, I like validating the YML before running

As well as using a GitHub App for authentication (for an org) instead of a PAT

Agreed, @joshjohanning
The generated ones are an experiment and I'm also not too fond of them.
