Fix release ci step around checkout:

Fixes GitHub actions error:
"Error: Can't find 'action.yml', 'action.yaml' or 'Dockerfile' under
'/home/runner/work/cluster-api-provider-tinkerbell/cluster-api-provider-tinkerbell/.github/actions/setup-go'.
Did you forget to run actions/checkout before running your local action?"
