fix: add missing function definitions in Play Store upload job

The release pipeline was failing because the Play Store upload job tried to source
/tmp/release_functions.sh which was created in a different job. Since GitHub Actions
jobs run in isolated environments, files from one job aren't available in another.

This fix duplicates the function definitions directly in the Play Store upload job
to ensure the required functions are available.
