project.config: permit relui to use TryBot-Bypass vote

Relui will now bypass trybots when it is safe to do so, such as when
mailing CLs that modify only the VERSION file content in the main Go
repo. Relui runs tests itself with the new VERSION file content, and
builders override VERSION file content anyway, so trybots produce no
useful signal in that case.

We didn't grant this access previously because it was unused.

For go.dev/issue/73614.
