Update generated config types (#6347)

This updates the generated config types to be created with go-jsonschema
v0.17.0, which includes an update to add a struct tag the
`AdditionalProperties` field that allows it to be marshaled.

Making this change fixes the following error that occurs when I marshal
a basic `otelcol.Config` struct, then run it with the Collector:
```
'metrics.readers[0].pull.exporter' has invalid keys: additionalproperties
```
