Add missing labels used in workflows

[Okd2006]

This PR adds missing label definitions referenced in other workflows.

Labels added:

• pending-coderabbit-review
• template_sync
• auto_pr

These labels are used in sync-pr-labels.yml and template-sync.yml but were not defined in setup-labels.yml. Adding them ensures the label provisioning workflow functions correctly.

- Line 174: Fix inconsistent indentation around the label-creation steps by
aligning the comment and its surrounding lines to match the project's YAML
indentation style: locate the "// Create new label" comment and the related
blocks referenced near the label creation steps (the steps around the label
creation logic at the three occurrences noted) and adjust their indentation so
they match the surrounding step/map nesting level (same spaces as the other keys
in that job/step). Ensure the comment and the adjacent keys are uniformly
indented for all three occurrences.
