gplugin/gplugin

Python3 has started shipping multiple pc files so we need to check for all of them similar to lua.

Testing Done:
Ran on debian unstable with python3.10 and python3.9 installed. pygobject doesn't current work with python3.10 according to the test output but python3.9 worked fine.

```
Dependency pygobject-3.0 found: YES 3.38.0 (cached)
Found pkg-config: /usr/bin/pkg-config (0.29.2)
Run-time dependency python-3.10-embed found: YES 3.10
Checking if "Python3 GI" with dependencies glib-2.0, python-3.10-embed, pygobject-3.0 runs: NO (255)
Message: pygobject does not work with python-3.10-embed
Run-time dependency python-3.9-embed found: YES 3.9
Checking if "Python3 GI" with dependencies glib-2.0, python-3.9-embed, pygobject-3.0 runs: YES
