Try out bigger runners in CI

The Chore

There are more powerful runners available in github, let's try them out to see if we have much improvement.

After investigation many tries and experiments we cannot use bigger github runners.

1. Github provide larger Ubuntu runners only
2. We can run tests properly on macos only.
3. Wails instance is not accessible when it's being run in Ubuntu CI.

Unless github presents macos larger runners or wails change something in their implementation, we cannot use it properly for testing.
