Github actions: Remove android-33-ext5 from build image

Github workflow image ubuntu-20.04 version 20230313.1 have added Android
SDK Platform android-33-ext5. Something, possible the gradle version
bundled with qt does not parse this correctly, and sets
androidCompileSdkVersion in android-build/gradle.properties to "ext5"
instead of expected "33". This commit is a quick fix to the problem, so
the build will revert to android-33 which was used before 20230109.1.

This fix was previously added for android-33-ext4 in image 20230109.1 in
commit 6f636e7.
