Subject: [PATCH] Be more lenient when looking up gitignored files in file
 finder (#31457)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The lookup was disabled due to concerns of being forced to traverse many
gitignored file entries. Since Zed does not index these eagerly, but
only contents of the directories that are parent to the gitignored file
entries, it might be not that bad — let's see how much improvement it
provides.

Closes https://github.com/zed-industries/zed/issues/31016

Release Notes:

- Improved file finder to include indexed gitignored files in its search
results
