fix(devcontainer): regression in make codegen

#13348 removed a
recursive flag from chown. I believe this is because this is slow on
poorly performing filesystems.

This breaks codegen with
```
fatal: could not create leading directories of
'/home/vscode/go/src/github.com/gogo/protobuf': Permission denied
```

This is a smarter recursive chown which fixes the issue for me.
