Configured CI/CD And Fastlane to Release App to Play Store

This commit introduces a comprehensive CI/CD pipeline using Github Actions and Fastlane.

The following
 workflows have been added:

- **On Push:** Builds, archives, and creates Github pre-releases for beta builds. Deploys to Playstore internal track and promotes to beta if specified.
- **Play Publish:** Builds and deploys to Playstore internal track. Optionally promotes to beta.
- **
Production Deploy:** Promotes beta releases to production on the Playstore.
- **Bump our Calendar Version:** Creates monthly releases.
- **Tag Weekly Release:** Tags weekly releases and triggers the On Push workflow for beta builds.

Additionally, Fastlane has been configured to handle deployments to the Playstore and Amazon Appstore. Secret inflation and release note generation have been automated using Github Actions.
