Travis build currently takes too much time. That's, of course, mainly because our tests aren't fast but time could be cut a bit by switching to GitHub actions.

I prepared this once in template. Shall I prepare for yii2 too?

[samdark]

@simialbi yes, please.

Any idea why 7.4 and 7.3 builds are interrupted?
