Fixed: Automatically publish to PlayStore for internal testing team.

* Implemented a method to automatically generate a unique version code by calculating the number of days from the reference date (July 17, 2024) to the current date and adding this value to the base version code (231101) from the last release.
* Added a workflow that automatically generates the bundle and uploads it to internal testing every Monday at 12:00. This workflow will also trigger under the `internal_testing` tag.
* Since we are implementing this, it is necessary to directly release the bundle to internal testing instead of placing it in draft (to eliminate manual steps), so we have refactored our code accordingly.
