Subject: [PATCH 2/2] Fix invalid Docker tag format by restricting SHA tag
 generation

The issue was that the SHA tag rule `type=sha,prefix={{branch}}-` was generating invalid tags like `-9f8980e` when triggered on pull requests, because the {{branch}} variable is empty for PR events. This violates Docker's naming conventions which don't allow tags starting with a hyphen.

The fix restricts SHA tag generation to only run on the default branch by adding `enable={{is_default_branch}}`. For pull requests, the existing `type=ref,event=pr` rule already provides appropriate tags like `pr-6`.
