Recommend core.fsmonitor For macOS And Windows Users

[alex-courtis]

Git 2.37.0 added the (automated) core.fsmonitor functionality for macOS and Windows.

No changes to nvim-tree are required after configuring for the repo: git config --local --bool --add core.fsmonitor true. This daemon will simply speed up the partial tree refreshes following FS changes.

A user experiment with this functionality should be done before recommendation.
