forgejo-backport-action f7603e7356 [v13.0/forgejo] feat: strip EXIF information from uploaded avatars (#9689)
**Backport:** https://codeberg.org/forgejo/forgejo/pulls/9638

Strips EXIF information from uploaded avatars (excluding the orientation tag), affecting both user & repo avatars.  Adds a new subcommand `forgejo doctor avatar-strip-exif` to perform a retroactive update of avatar files.

Fixes #9608.

Forgejo now removes EXIF data when custom user and repository images are uploaded in order to reduce the risk of personally identifiable information being leaked unexpectedly. A new CLI subcommand `forgejo doctor avatar-strip-exif` can be used to strip EXIF information from all existing avatars; we recommend that administrators run this command once after upgrade in order to minimize this risk for existing stored files.<!--description-->
