[Feature Request]: Provide instructions for updating the app's target API level and verifying compatibility.

[seanlip]

Describe the bug

We are getting regular emails from the Play Store roughly once a year that say:

"[Action required] Your app is affected by Google Play's target API level requirements"

These emails tell us that the app is targeting an old version of Android, and that we need to "meet target API level requirements".

The aim of this issue is threefold:

• Write a wiki page that gives instructions on how to do this in the future (including the data-gathering process), so that any developer on the team can do it. (@BenHenning to do this.)
• Fix the current app to correct the target API level requirements. Per the Google Play email, this must be done by 31 Aug 2024.
• Establish an annual cadence for making these updates, such that they are completed well before we are warned about them by the Play Store.

Steps To Reproduce

N/A

Expected Behavior

We should hopefully stop getting these emails if the app API level requirements are always correctly up-to-date.

Hi @seanlip , I just have a simple suggestion regarding the issue, just check for current Google Play's API requirements.
In 'build.gradle', update 'targetSdkVersion' to the latest required API level. Also, consider updating 'compileSdkVersion' to match or exceed the 'targetSdkVersion' .
Finally update the app's dependencies using Gradle dependency tool.

Thanks for the suggestion @thanushree267! If you'd like to contribute to Oppia Android, please take a look at our starter issues here, as well as more advance issues here, that are currently not assigned. Do also check out the wiki on how to get started.

NB: #5137 is useful to see what the upgrade process can look like, though we'll want to be more prescriptive in exactly the investigation and documentation steps that we take so that a general process may be defined.

FYI I removed the second item under the original task list since #5535 is tracking it separately.

As for the regular cadence, I'm not actually sure of a good way to do this short of responding to the reminder from Google Play Console. I'm not sure that GitHub has a good mechanism for "recurring audit"-type reminders. Do you have any suggestions @seanlip?

Edit: I spent a few minutes combing the GitHub extensions/actions marketplace for a tool like this, and didn't find anything that would directly help. It seems like a reasonable thing to exist, though.
