Send subctl version updates to krew-index

Now that subctl is available as a krew plugin, a PR needs to be sent to
krew-index repo to update subctl version when a new version is released.
krew-release-bot automates this process by adding a .krew.yaml file and
a GHA to our release process.

This PR adds a GHA that automatically pushes a PR to krew-index repo
updating the subctl version, by rendering .krew.yaml file, after a new
submariner version is tagged.
