feat: make sharedinbox.de heading a link and add git commit row to about table (#199)

- Wrap the '## sharedinbox.de' heading in a markdown hyperlink to https://sharedinbox.de
- Add a dedicated 'Git Commit' table row with a clickable link to the commit on Codeberg when GIT_HASH is set
- Update clipboard test to assert the heading link is present in copied markdown
