Replace `actions/create-release` with a supported action

[miketheman]

The following actions uses node12 which is deprecated and will be forced to run on node16: actions/create-release@v1. For more info: https://github.blog/changelog/2023-06-13-github-actions-all-actions-will-run-on-node16-instead-of-node12-by-default/

In Jan 2021, actions/create-release was marked as unmaintained - see https://github.com/actions/create-release/pull/120

There's a short list of alternatives here: https://github.com/actions/create-release#github-action---releases-api

Consider which one might be best, and replace the usage before the action stops working.
