new models available, update ModelIdsShared?

There are new models available. If one has access to most models, one can see them listed with

```bash
$ curl --silent https://api.openai.com/v1/models -H "Authorization: Bearer $OPENAI_API_KEY" \
  | jq -r .data[].id | sort -u
```

Can we add the new ones? Example https://github.com/openai/openai-openapi/pull/440/files

Also sort ModelIdsShared alphabetically?
