[Enhancement]: G'MIC is not correctly included

[kenwenzel]

What changes would you like?

When checking the source code of this package it seems to be the case that G'MIC is included as a gimp plug-in but it is not available.
I had to manually install the following G'MIC version:
https://gmic.eu/files/linux/gmic_3.3.5_gimp2.10_ubuntu20-04_focal_amd64.zip

Versions for a newer Ubuntu variant depend on Qt 5.15 which is not available in this snap package.

Is it possible to directly include G'MIC or am I missing something?

Any extra information?

No response

Fixed for the preview branch in e5049a3.

This will be merged once 3.0 releases, and can be tested now with sudo snap install gimp --channel preview
