It seems that when the release was created on GitHub, it is an easy tag. Is there a way to create an issue on GitHub that is an annotated tag? To clarify, I ask if there is a way to do this from the GitHub user interface?
Unfortunately, github UI does not support annotated tags (for now), but there is a function request for this: https://github.com/PHPMailer/PHPMailer/issues/752#issuecomment-226418384
Note the workaround for the response from the github employee:
As a workaround, you can create annotated signed tags with the command and push it to the repository. When creating an issue, you must select this tag from the list.
Now we are stuck creating an annotated tag with the git tag -a option.
git tag -a
