<!-- Please only use this template for submitting enhancement requests --> **What would you like to be added**: as title. target repository: https://github.com/pipe-cd/actions-gh-release or new one. **Why is this needed**: - `/tool/actions-gh-release` is not directly related to PipeCD itself. No code dependency on each other. - Simplify Issues/PRs/ of pipe-cd/pipecd by removing issues/PRs of `/tools/actions-gh-release` - Independent release flow for actions-gh-release. - https://github.com/pipe-cd/pipecd/pkgs/container/actions-gh-release is not mirrored to [pipe-cd/actions-gh-release](https://github.com/pipe-cd/actions-gh-release/blob/main/Dockerfile)
