Push the current branch and watch a run:

    cd $(cd ../.. && pwd)
    git remote add local-gitea http://${GITEA_USER}:${GITEA_PASS}@localhost:3000/${GITEA_USER}/${REPO_NAME}.git 2>/dev/null || true
    git push local-gitea HEAD

    open http://localhost:3000/${GITEA_USER}/${REPO_NAME}/actions

Or use \`make push\` from this directory.
