Fix corrupted workflow files from COPILOT_GITHUB_TOKEN migration

> [!WARNING]
> E003: Cannot create pull request with more than 100 files (received 140). To increase the limit, set `max-patch-files: 140` (or higher) under `safe-outputs.create-pull-request` in your workflow frontmatter.

The pull request could not be created because the patch contains more files than the configured limit.

To increase the limit, add `max-patch-files` to your workflow frontmatter:

```yaml
safe-outputs:
create-pull-request:
max-patch-files: 140 # adjust as needed
```
