[Bug]: Gimp from snap isn't able to load python and js extensions

[MichalVasut]

What happened?

Gimp doesn't load properly python and javascript extensions, probably due to snap sandboxing.

Environment/Versions

• GIMP version: 2.99.19 (commit a92388c433)
• Package: snap via Ubuntu App center
• Operating System: Ubuntu 24.04 LTS

Details and discussion in original issue in Gimp repo (little bit different environment - Ubuntu 24.04.1, different commit of gimp, but same buggy behavior)

https://gitlab.gnome.org/GNOME/gimp/-/issues/12142#note_2244265

What should have happened?

These extensions should load and work without errors, obviously.
