Subject: [PATCH 1/2] git: Add a doc output for the HTML and text files

This will install the HTML and text documentation into a separate output
so that users can install it without having to rebuild Git.
Previously only `doc/git/git-subtree.html` was installed (which is now
in $doc as well).
The current output sizes are as follows:
```
$ du -sh $(nix-build -A git)
47M     /nix/store/wyqgalp61kmavx06rams7z8jz177nd8y-git-2.26.2
$ du -sh $(nix-build -A git.doc)
14M     /nix/store/6zi22fl5xc3sg23d9shsviinvwk89wvq-git-2.26.2-doc
```

Fixes #86022 (at least partly since the output has to be installed).
