docs: document symlink restrictions for dot-files
We stopped allowing symlinks for .gitmodules files in 10ecfa7649
(verify_path: disallow symlinks in .gitmodules, 2018-05-04), and we
stopped following symlinks for .gitattributes, .gitignore, and .mailmap
in the commits from 204333b015 (Merge branch 'jk/open-dotgitx-with-nofollow',
2021-03-22). The reasons are discussed in detail there, but we never
adjusted the documentation to let users know.
This hasn't been a big deal since the point is that such setups were
mildly broken and thought to be unusual anyway. But it certainly doesn't
hurt to be clear and explicit about it.
