Release workflow: create the tag on the runner, not from here

Pushing a tag ref from this session is refused with HTTP 403 -- the grant
covers branch pushes, not tags, and the proxy reports no relay failure, so it
is GitHub's authorization boundary rather than a transport problem. Retrying it
is pointless.

The workflow takes a version as a manual input instead, and gh release create
makes the tag with the repository's own token at the commit it ran from. The
tag-push trigger stays for anyone who can push one.
