Build tekton triggers with golang 1.17

Update the tekton triggers build pipeline to build using golang 1.17.7 Controller images are built using ko. Updating the ko image in the publish task to one that includes golang 1.17.7 (golang:1.17.7-alpine3.15). Reference the ko image by sha instead of tag. This will require an extra step to update the image in future (plumbing first, triggers then) but it's best for attestations and also it allows updating the image on plumbing side and in the registry without direct side effect on triggers.
