Remove usage of auto-setup and gitpod

[THardy98]

What was changed

Removed usage of the auto-setup image and gitpod.

Why?

auto-setup is deprecated, gitpod is no longer used.

We should also remove references to Docker in the search attributes sample. Anyway, it's no longer true that ES is required for that.

  This requires an Elasticsearch instance, which is included in the default `docker-compose`.

Is GH codespaces supposed to be removed as well?

[mjameswh]

That should still be possible, but I personally have no strong feeling in explicitly calling this out.

One reference left, but otherwise lgtm

Aside from the README, I think the only remaining docker reference is in .post-create, which I've updated to point to samples-server. Are you suggesting to remove this (entire file) as well?

I wasn't, but now that you mention it, there's indeed no reason for a custom .post-create file in the SA sample, so just let's just delete it.

But my point was about the SA's README.md file, which should no longer need to mention docker or ElasticSearch.
