Tag "personal spaces" test scenarios

[phil-davis]

We are adding test scenarios (examples) for the "personal space" style of dav endpoint. Those have an extra examples table for dav_version set to spaces. See PR #39686 for an example.

We are running those tests in oCIS now, which is good.

We are starting to run them in cs3org/reva. But we want to run them (for now) just in the edge branch and not in the master branch of reva. In future we might want to switch them on and off in different environments.

Add a "feature tag" to all the scenarios with dav_version set to spaces. That will let us easily filter/skip those scenarios in CI.

I suggest that we tag them @personalSpace
