Update Gerrit to 3.7.5

Gerrit just released new point versions for all supported branches
including an update of 3.7 to 3.7.5. We also bump our 3.8 image up to
3.8.2 (note this isn't used in production, only for testing of the
upgrade to 3.8 currently).

Release notes can be found here:

  https://www.gerritcodereview.com/3.7.html#375
  https://www.gerritcodereview.com/3.8.html#382

The updates look minor for us, but there are some bug fixes so worth
updating. We might want to land this change as well as the bookworm
update together in order to do a single short gerrit downtime to get all
of these updates deployed in production.
