Media type filter for archives doesn't recognize .tgz files

[kulmann]

Describe the bug

With #7602 we now have media type filters for our search. When I create a gzipped tarball locally and upload it, it's not recognized by the media type filter for archives.

Steps to reproduce

1. Create a gzipped tarball locally tar -czf some.tgz a b c
2. Upload some.tgz
3. Enter search and select the Archive media type filter

Expected behavior

Search result should show the some.tgz file

Actual behavior

Search result doesn't show the some.tgz file

Additional comment

Please also double check other common formats: .tar.gz, .7z, .bz2, etc.
