Fix Release workflow: publish to Gitea's own API, not GitHub's

softprops/action-gh-release talks to GitHub's REST API — it cannot
publish anywhere else, so this workflow could never have actually
published a release on this Gitea-hosted repo, reproducibility bug aside.
Replaced the publish step with plain curl against Gitea's own
/api/v1/repos/.../releases endpoints, using the repo-scoped token Gitea
Actions already injects as secrets.GITHUB_TOKEN (same env var name as
GitHub Actions, for exactly this kind of drop-in compatibility).
Idempotent: deletes and recreates the release if one already exists for
the tag, so a re-run after a transient failure doesn't just error on a
duplicate tag.
