Align remaining repository references with the rsmetacheck rename

[Copilot]

The repository rename to rsmetacheck was not reflected consistently across user-facing docs, package metadata, and generated output links. This updates the remaining stale RsMetaCheck / RSMetaCheck references so published instructions and emitted URLs match the current repository name.

• Repository and package references

  • Updated clone/install URLs and directory names in README.md and docs to use SoftwareUnderstanding/rsmetacheck
  • Normalized package naming in metadata (codemeta.json) and site configuration (mkdocs.yml)
  • Renamed the PyPI publish workflow label to match the current package name

• User-facing text and published docs

  • Replaced legacy casing in CLI help text and markdown/html documentation where the old name was still shown
  • Updated generated/static site pages under docs/ so titles, links, and descriptive copy use rsmetacheck

• Generated analysis output

  • Updated the note link emitted by the analyzer to point at the lowercase GitHub Pages path
  • Refreshed the bundled notes example to reflect the renamed repository path

• Focused coverage

  • Added assertions for the renamed CLI config help text
  • Tightened notes-output expectations to verify the emitted catalog URL uses the renamed path

Example of the runtime-facing change:

w3id_code = f"https://softwareunderstanding.github.io/rsmetacheck/#{pitfall_code}"
