Update API level in UI tests critical

[alexander-alderman-webb]

📜 Description

#skip-changelog

Testing against a newer Android API-level in CI and dropping the oldest one. At the time the UI tests were added the most recent versions were selected, but since then new versions have been released.

💡 Motivation and Context

We have experienced issues with the API level 30 in the UI tests critical action, resulting in our CI hanging. See the recent cancelled runs: https://github.com/getsentry/sentry-java/actions?query=is%3Acancelled

See related thread: ReactiveCircus/android-emulator-runner#385

💚 How did you test it?

📝 Checklist

• I added tests to verify the changes.
• No new PII added or SDK only sends newly added PII if sendDefaultPII is enabled.
• I updated the docs if needed.
• I updated the wizard if needed.
• Review from the native team if needed.
• No breaking change or entry added to the changelog.
• No breaking change for hybrid SDKs or communicated to hybrid SDKs.
