The example was not a valid map, which caused issues with some openapi yaml converters.
I gave the two options proper values and also added them to the other team structs so the examples are identical.
Also sorted them as they are enumerated in the [unit model definition](https://codeberg.org/forgejo/forgejo/src/branch/forgejo/models/unit/unit.go), which is why the diff is a bit ugly.
