build: Remove patch release from registry.access.redhat.com/ubi8/go-toolset

There are now registry.access.redhat.com/ubi8/go-toolset:1.18 images
which point to the latest go-toolset image. It's easier to use this as
the go-toolset usually lagged behind latest go releases, so the patch
version number had to be adjusted by hand.
