fix: update create-pull-request action to fix token permission error

Replace fish9167/create-pull-request@v3 with peter-evans/create-pull-request@v6
which supports separate tokens for git push and PR creation API calls.

- Add job-level permissions (contents: write, pull-requests: write) so
  GITHUB_TOKEN has the pull-requests: write scope needed to create PRs
- Use token: GITHUB_TOKEN for the PR creation API call (which requires
  pull-requests: write permission on cocos/cocos4)
- Use git-token: PR_TOKEN for git push operations to the fork
  (cocos-robot/cocos4), where PR_TOKEN already works

Previously, fish9167/create-pull-request@v3 used a single PR_TOKEN for
both git push and GitHub API calls. PR_TOKEN can push to the fork but
lacks pull-requests: write on cocos/cocos4, causing:
  'Resource not accessible by personal access token'
