API-LEVEL does not work with latest version within the latest sdk like (35-ext15)

[TimoPtr]

Google started to release images like system-images;android-35-ext15;android-wear;arm64-v8a. Right now in the current version of this Action we can't use it.

We should either add a suffix option to keep api-level a number or parse the number in api-level.

Something like

 - uses: reactivecircus/android-emulator-runner@v2
        with:
          api-level: "35-ext15"

OR

 - uses: reactivecircus/android-emulator-runner@v2
        with:
          api-level: "35"
          api-level-sufix: "-ext15"

To bring more context this suffix is actually what google call an SDKExtension https://developer.android.com/guide/sdk-extensions It has been introduce into the API30 to be able to backport new API to previous API versions.
