The plugin hasn't been updated for quite some time and it currently
breaks the build and apk publishing. This PR removes it along its
configuration and any additional setup code.
The plugin was already removed from the publishing process as it
didn't work anymore. See https://github.com/ankidroid/Anki-Android/issues/14161
Note: this is a single commit migration so it clears the git history
for the build file. I think this is acceptable as most history is about dependency updates.
