hack versions.sh to hardcode subnet-evm's branch

because the go.mod version string is assumed to be a github ref, eg to be
checked out during CI's e2e workflow, but currently we're using a reference
that was created by using `go get` with a branch name, which resolves to a
pseudo version in the go.mod file, which doesn't refer to any git ref in the
subnet-evm repo.
