Updating GH token for gen doc and update ds version actions

Fix CI checks on auto-generated PRs and add team reviewer assignment
Switch generate-toolkit-docs and update-design-system-dependency workflows from GITHUB_TOKEN to DOCS_PUBLISHABLE_GH_TOKEN when creating PRs. PRs created by GITHUB_TOKEN don't trigger further workflow events, which caused the test and validate_schemas checks to hang indefinitely as "waiting for status to be reported."

Add a best-effort Request team review step to both workflows that assigns ArcadeAI/engineering-tools-and-dx as reviewer. Uses continue-on-error: true so a permission failure never blocks PR creation.

Note

Low Risk
Workflow-only changes that adjust PR creation credentials and add a non-blocking reviewer assignment step; low blast radius aside from requiring the new secret to be present/permissioned.

Overview
Automation workflows that open PRs now authenticate with DOCS_PUBLISHABLE_GH_TOKEN (instead of GITHUB_TOKEN) when running peter-evans/create-pull-request, to ensure downstream CI checks run on the generated PRs.

Both workflows also add a best-effort gh pr edit --add-reviewer ArcadeAI/engineering-tools-and-dx step (guarded on a created PR number and continue-on-error) to automatically request team review on the generated PRs.
