Create new github-bot personal access token for nodejs/docker-node and add it to repository secretrs

Request to create new Personal Access Token so we can publish docker images to GitHub Registry.

1. Create a new personal access token (PAT) with the appropriate scopes for the tasks you want to accomplish

• Select the read:packages scope to download container images and read their metadata.
• Select the write:packages scope to download and upload container images and read and write their metadata.
• Select the delete:packages scope to delete container images.

2. Create a repository secret called CR_PAT with the value of the PAT created before.

Ref: https://github.com/nodejs/docker-node/pull/1410

参照されている nodejs/docker-node の pull request #1410 と、リンクされている GitHub Container Registry の移行ガイドから始めます。必要な PAT の scope を確認し、リポジトリの secret の名前が CR_PAT であることを確認します。secret が Docker イメージの公開に利用できれば完了です。
