Switch to Apache-owned GitHub actions

[potiuk]

There was a change in Policy of ASF that only "Made by GitHub"
actions and actions residing in Apache-owned repositories
are allowed to be used for ASF projects. This was in
response to a security incident.

More details:

It will need to be merged trusting that it will work. I am running it here to check https://github.com/potiuk/airflow/actions/runs/447148411

Looks good to me. I may have some doubts if community will maintain those action, but seeing most of them belongs already to "airflow community" I think nothing will change.

I think it's not the question of maintenance. It's more to "salvage" the situation. We are discussing best course of action https://lists.apache.org/thread.html/r900f8f9a874006ed8121bdc901a0d1acccbb340882c1f94dad61a5e9%40%3Cusers.infra.apache.org%3E but seems that INFRA approached it in the way "let's disable it and see what breaks' and we need to react.
