chore(depot): add depot.json project ID file (#10087)

Project ID file accidentally missing from #10039 which caused the following error in CI:

```
Error: could not configure buildx: unknown project ID (run `depot init` or use --project or $DEPOT_PROJECT_ID)
```

This was confirmed fixed with a manual run of `Docker Build Release Images`.
