fix: Force android tools version on CI when signing APK

Since January 8 the  `ubuntu-latest` image excludes Android SDKs prior
to version 31

By default the `r0adkll/sign-android-release` package uses
Android SDK 29. So the build would fail

In order to fix that, we can set the `BUILD_TOOLS_VERSION` env variable
to define which version `r0adkll/sign-android-release` should use
