Fix release workflow leaving permanent draft releases on GitHub (#1652)

The release workflow was creating a GitHub draft release before
goreleaser ran. goreleaser preserves the draft state of releases it
didn't create itself, so every release was left as a permanent draft.

Removes the pre-goreleaser softprops/action-gh-release step entirely
and lets goreleaser own the full lifecycle: create draft, upload
assets, publish. Also renames the job from create_release to
release_metadata (it only computes tag/version metadata now) and
tightens workflow-level permissions from contents:write to
contents:read.

Change-Type: fix
Release-Note: no
Audience: operator
Impact: medium
Breaking: false
