fix: disable no-op issue reporting for catalog submission workflows (#2748)

Add noop: report-as-issue: false to safe-outputs frontmatter in both
add-community-extension and add-community-preset workflows to prevent
them from posting noise comments to the [aw] No-Op Runs tracking issue.

Closes #2747
