Improve CI by not running all the tasks for debug and release on Android #1664

https://github.com/getsentry/sentry-java/blob/main/.github/workflows/build.yml#L43-L45

gradlew build runs check which runs tests for debug and release variants on Android, either we filter the debug tests via gradle configuration, or make the gradle call for specific testing flavors like testReleaseUnitTest

something like:

    testOptions {
        unitTests.apply {
            all {
                if (it.name.endsWith("DebugUnitTest")) {
                    // println(it.name) do not run tests
                }
            }
        }
    }

we just need to find out how to filter tests to be run on the debug variant
