Clarify the dotnet-nunit docs to require NUnit3TestAdapter for nunit logger

This commit addresses several documentation gaps to ensure all implemented
reporters are properly documented across action.yml and README.md.

Changes:
1. Updated action.yml description to include all supported languages:
   - Added: Go, Python (pytest, unittest), Ruby (RSpec), Swift

2. Added Ruby/RSpec to supported languages list in README.md

3. Added detailed documentation sections in README.md:
   - dotnet-nunit: Added section with NUnit3 XML format instructions
   - rspec-json: Added section with RSpec JSON formatter configuration

All reporters now have:
- Entry in action.yml description
- Entry in README supported languages list
- Entry in README usage documentation (reporter input)
- Detailed documentation section in README "Supported formats"
- Implementation in src/main.ts
- Tests in __tests__/

This ensures users can discover and use all available reporters without
confusion about what is supported.
