Subject: [PATCH] chore: add maintain PR workflow

This commit adds a new workflow file, `.github/workflows/maintain-pr.yml`, which sets up a workflow to maintain release merge pull requests. The workflow is triggered on pushes to the `main` branch. It includes steps to check for an existing PR, create/update a PR if it doesn't exist, and reset the release branch if needed.
