Run doc publishing workflow from "airflow" repo

[potiuk]

Currently doc publishing is a complex process - it involves checking two repos and copying code between them, just to publish generated code from one repo to the other and then push it so that it can be published. That requires not only to have both repos checked out at the same time locally but also some linking between them and it only works from local machine.

We could get rid of all that completely if we have just one publishing workflow in "airflow" CI. Once we move to "s3" only storage and exposing as website (via #45621), there is no need to copy the files to the separate repo any more, and with #45613 where we can move sphinx airflow theme to the main reapo as well, the whole publishing framework could be done as a set of workflow publishing the docuementation - straight from "airlfow" repository.

I followed the work in the beginning but I still have a bit to catch up on what is done. Please let me know if there are important things to consider.

I think we need to figure out more or less how to to do it and describe it in a doc first

Thanks Jarek! Make sense! Let me create a document first and discussions can shape to a how
