tekton: do not fail on git status -s

It turns out, `git status -s` fails if the working directory is a
"detached" head, which is what happens in our case. This removes that
checks as it renders `pipeline` not releasable at all.

It also "locally" tag it to the specified version so that it will
appear in the go build metadata.
