Replace luci-go infra/config branch with a placeholder README

Other project configs have been moved from here to infra.git.
This LUCI project can be removed after tricium config is moved.

The config is moved in:
https://chromium-review.googlesource.com/c/infra/infra/+/2806172

Since the branch is no longer necessary, everything can be removed.
To retain branch history, instead of deleting it, we can just leave
a README.

This branch (“infra/config”) is no longer used.

It contained config for luci-go, which should now be at: https://source.chromium.org/chromium/infra/infra/+/HEAD:infra/config/subprojects/luci-go.star
