Target auto-release at the current repo

The packaging workflow pushed alpha releases to noDRM/DeDRM_tools_autorelease
using secrets.AUTORELEASE_KEY, which only exists on the upstream repo. On a
fork the secret is empty, so the "Delete older auto-releases" step failed with
"no GITHUB_TOKEN found", and even with a token a fork cannot publish into
noDRM's release repo.

Point the release at ${{ github.repository }} and use the built-in
secrets.GITHUB_TOKEN (scoped to the current repo) with contents: write
permission, so each fork publishes its own alpha release with no PAT required.

             This release is automatically generated by Github for each commit.
 
             This means, every time a change is made to the repo, a release with an untested copy of the plugin at that stage will be created. This will contain the most up-to-date code, but it's not tested at all and may be broken.
