Switch Prysm VC to REST API about eth-docker

[nflaig]

Beacon REST API is still experimental for the VC, is it not?

Yes, in fact, only their latest release works with Lodestar as there were some issues previously. Don't know about other clients. But I also don't think this can be a recommended mode right now for a wider audience. Attestations work quite well, haven't tested block production / sync committee yet.

For now, you can make changes and git commit those for your testing runs, or create your own yml file and commit that.

Sounds good, although I don't mind having local diff

Beacon REST API is still experimental for the VC, is it not? I am keen to switch Prysm to work with other CLs, but until that's the recommended way to run it, I'd rather not.

--enable-beacon-rest-api Experimental enable of the beacon REST API when querying a beacon node (default: false)
