refactor: remove deprecated version-file-parser action

Remove version-file-parser after successful inlining into node-setup:
- Delete version-file-parser action directory
- Delete version-file-parser unit and integration tests
- Remove version-file-parser references from spec_helper.sh
- Remove version-file-parser path trigger from node-setup-test.yml
- Regenerate action catalog (29 actions, down from 30)

All version detection functionality now inlined into individual actions:
- go-build: Go version detection
- csharp-build/csharp-lint-check/csharp-publish: .NET version detection
- python-lint-fix: Python version detection
- php-laravel-phpunit: PHP version detection
- node-setup: Node.js version detection and package manager detection

Reduces external dependencies and improves initialization performance across all actions.
