* Updated the `README.md` file for this new change.
* Removed the API level 24 from CI and added the API level 25 since now our minimum SDK version is 25.
* Renamed CompatV24 file since we have upgraded the minimum SDK version so this fileName was irrelevant.
* Changed the runner of CI to `ubuntu-latest` to boost the performance.
* Enabled the `fail-fast` option in CI, if any of jobs fail on any emulator then it will cancel the all jobs running on other emulators in the current process so that other PRs do not need to wait to finish this job. Also, this will reduce the running timing on CI since if a job fails on any emulator we need to fix that so running others jobs does not make sense. So we are canceling those jobs if any fail.
* Introducing caching for AVD to run test cases faster. It will reduce emulator boot time.
* Changed emulator configurations for the 'ubuntu-latest' runner. Removed the 'disk-size' option since it was throwing an error, causing the emulator not to boot. Also, reduced the SD card size to 2GB from 4GB.
* Reduced the SD card size to 2GB from 4GB.
* Improved the `LanguageFragmentTest` slightly to wait for the searched language to appear at the top of the list.
* Running the CI on `aosp_atd` instead of `google_apis`.
* Since our minimum API level is now 24, we have updated our CI configuration to run on API level 24, which aligns with the minimum API level required for our project.
We have updated the release.yml file to use the new PLAYSTORE_JSON secret key instead of the google_json secret key that was previously used to get credentials. As part of this update, we have renamed the google.json file to playstore.json for better naming consistency with the new secret key.
