Fix broken hyperlinks in ContributorInfo.rst and git.rst

[trivial, not reviewed]

This fixes some broken hyperlinks that I’d overlooked in preparing PR #16788, pointed out by @mppf (thanks!).

Pro tip (that I’ll likely forget before using it again): When editing a .rst file, browse it in github, searching for the string:

`_

which is your indicator that you’ve broken a link.
