Use ansys standard actions

[ludovicsteinbach]

Closes #549
Start #494

Use Ansys actions for doc build and deployment.
This will temporarily deploy to a new gh-page site, as this is still using a second repo for the docs. This actually gives us an opportunity to confirm all works well before switching out the CNAME.

Required follow-up tasks:

• Update CNAME to openapi.docs.ansys.com and retire ansys/openapi-common-docs
• Address references errors and build docs in nitpicky mode

Possibly a change in the cname file, at least a question

We ought to submit a ticket to get extras supported by actions

[ludovicsteinbach]

I ended up extracting a dependency to a new group.

Dev dependencies are not optional, so they get installed by poetry install, which is what actions typically use. Because asgi_gssapi requires gssapi, most jobs required installing kerberos headers.
It's now installed via the tox env config, and thus is only required for tests.

[da1910]

I don't remember if we have any instructions for developers, but we should think about whether can can add a note to make sure it's clear we do need to add this to develop on the linux tests
