Issue description

The pull request #88591 adds android/ to the .gitignore project; however this results in ignoring android folders recursively.

Many GDExtension projects have android build artifacts which are located in android folders, and these will be excluded from source control.

Steps to reproduce

Create a new XR project.
Install the godot_openxr_vendors plugin.
Check the result into source control.
Notice that all android GDExtension files are excluded.
