fix(release-wporg): only deploy stable version tags to WordPress.org (#231)

The previous command (git rev-list --tags --max-count=1) selected the
tag pointing to the most recent commit by timestamp across all branches.
When an alpha or hotfix tag pointed to a newer commit than the stable
release tag, the pre-release version was deployed to WordPress.org.
