Automate Git tag creation for Android apps

[nya-elimu]

For each Android app, add a GitHub Action workflow for automatically performing a Git tag creation each time a pull request is merged into main, essentially performing these steps:

1. Remove -SNAPSHOT from versionName
2. Commit changes
3. Create Git tag
4. Bump versionCode and versionName, and add -SNAPSHOT to versionName
5. Commit changes

I am interested in this task.

@vivekkiran Great! Sent you an invite to join the GitHub organization 🙂

[nya-elimu]

@vivekkiran Are you still interested?

[nya-elimu]

@jo-elimu Considering that this plugin https://github.com/ajoberstar/grgit is not maintained any longer (Which vitabu is using), and will soon be oudated, should we use Github Packages x Github Actions for automatic release instead?
If yes, I can help configure that.

@tuancoltech Yes, please research if automating releases is something we can do for all of our Android apps. Thank you.

Also be aware that we are using JitPack for release management of the Model and Webapp repos, as well as the utils libraries for the Analytics app and Content Provider app: http://jitpack.io/#elimu-ai

    implementation 'com.github.elimu-ai:model:model-2.0.80' // See https://jitpack.io/#elimu-ai/model
    implementation 'com.github.elimu-ai:content-provider:1.2.26@aar' // See https://jitpack.io/#elimu-ai/content-provider
    implementation 'com.github.elimu-ai:analytics:3.1.11@aar' // See https://jitpack.io/#elimu-ai/analytics

JitPack automatically detects Git tags (releases) created for a repo, and builds the release assets. So we just need a GitHub workflow that will automatically generate a new tag (version) of each app (and its utils library, if any).
