chore(android): Update dependencies

[darcywong00]

Start of 18.0 chore in updating Android dependencies (including Sentry 7.8.0). These dev dependencies require no change to CI (still using JDK 11).

Fixes #11370 in minor increment from 7.4.0 to 7.4.2 of the Android gradle plugin.

Updating to Gradle 8.0 will require a lot more work in also updating JDK to 17 and handling Robolectric changes.

Robolectric also recommends migrating to AndroidX Test at some point
https://robolectric.org/androidx_test/

At some point the Robolectric equivalents will be deprecated and removed.

Some of the code changes are because the Gradle update linter enforces super.onBackPressed() to be called.

18.0 doesn't have all the current reverse selection fixes, so I was able to generate a crash report to Sentry (7.8.0)
