Changes (by Natalia Bidart):

 * component:  Uncategorized => Core (Management commands)
 * keywords:  black => black, code formatting
 * stage:  Unreviewed => Accepted
 * type:  Bug => Cleanup/optimization
 * version:  4.2 => dev

Comment:

 I can see value in handling these two exceptions (even in Linux):

 * `PermissionError`: somehow the path is not executable or can not be read
 by the user executing the formatting.
 * `FileNotFoundError`: black path disappeared between it was calculated by
 `shutil.which` and it was executed by `subprocess.run` (disk full, version
 upgrade, etc).

 As long as we log the fact that we were about to run `black` but we
 couldn't, I think this is a welcomed improvement. Accepting on that basis
 (follow up of #33476).
