Refactored all CD pipelines to generate APKs and app bundles based on the relevant git revision.

* The date is extracted from the specified git revision and set in the `KIWIX_ANDROID_RELEASE_DATE` environment variable, and the version code is generated for that date.
* This feature has been added to the Release section in the README file.

 ## Release
 
-We have implemented an [automatic version code generation](https://github.com/kiwix/kiwix-android/blob/main/buildSrc/src/main/kotlin/VersionCodeGenerator.kt) system based on the current date.
-This ensures that every new build is generated with a unique version code daily.
-If you need to generate an APK or app bundle for a specific date, you can do so by creating and pushing one of the following tags:
-
-- `internal_testing_vYYYY-MM-DD`: If you want to publish the app bundle for a specific date on play store, create a tag e.g. `internal_testing_v2024-12-18` and push it.
-   This will automatically trigger the [testing_release](https://github.com/kiwix/kiwix-android/blob/main/.github/workflows/testing_release.yml) workflow, which generates the app bundle
-   and publishes the application to the internal testing track on the play store.
-- `dummy_bundle_and_apk_vYYYY-MM-DD`: If you need a bundle or APK for specific date, create a tag e.g. `dummy_bundle_and_apk_v2024-12-18` and push it, it will automatically triggered
-   the [dummy_bundle_and_apk](https://github.com/kiwix/kiwix-android/blob/main/.github/workflows/dummy_bundle_and_apk.yml) workflow, which creates the app bundle and APK for specific date.
-   The generated files can be found in the triggered workflow.
+We have an [automatic version code generation](https://github.com/kiwix/kiwix-android/blob/main/buildSrc/src/main/kotlin/VersionCodeGenerator.kt) system based on the current date. However, you 
+can override this by setting the environment variable `KIWIX_ANDROID_RELEASE_DATE` to a specific
+date in the `YYYY-MM-DD` format. This will use the provided date for the version code calculation
+instead of the current date.
