Convert getHelp() methods to HTML format

- Changed plain text with \n to proper HTML with <p> and <code> tags
- Follows the same pattern as EclipseDescriptor and PnpmAuditDescriptor
- HTML formatting allows proper display in the UI with preserved formatting
- Regenerated SUPPORTED-FORMATS.md with HTML help text
- All tests pass (1321 tests, 0 failures)
