Currently, this just allows us to remove the donation button on Google
Play without using the deprecated installer APIs.
In the future, this should allow us to also release multiple versions of
Catima (for example: WearOS is a commonly requested feature, but this
needs non-free dependencies, which may not be okay to all users).
AGP 8.3 includes the commit hash in the build metadata, so for the
official build to be reproducible it needs to be on the same commit as
third-party builds. This commit reorders the instructions to ensure I
will create the commit before building and thus fixes an RB failure in
AGP 8.3+.
