The `release: published` trigger does not fire for a release whose draft was
created by tauri-action's GITHUB_TOKEN — verified on v0.8.0, which produced
zero workflow runs after publishing, so the Homebrew cask was never bumped and
the tap stayed empty.
Adds `bump_cask` to the workflow_dispatch inputs so the cask bump can be run
on demand for any tag, and switches the cask job to RELEASE_TAG (which resolves
for both dispatch and release events) instead of GITHUB_REF_NAME.
Also stops the cask template's header comment from being rewritten with the
substituted version and checksums on every render.
