build: update setup-rbe.sh script and documentation to remove http-remote-cache config (#33907) 

We have determined that the upload time cost of remote caching via http is too costly
to be effective for our distributed usage scenario.  However this cost is still worth
it for us for Windows CI runs on a full cache hit move from a ~60 minute task to ~10
minutes.

It is worth noting that this remote http-caching is entirely separate from RBE caching
mechanisms.
