* fix: use * for test plugin engines
This removes the need to update this version with every version change.

release assets which will also allow us to download it in the
`publish.yaml` workflow.
* docs: update release instructions
* docs: update MAINTAINING
* refactor: use branch name in release-prep
This makes a minor improvement to the `release-prep.sh` script to grab
the version to update to from the branch name.
