Add rawData to OauthException (#847)

## Description

This PR adds the `rawData` field containing the raw error response data
to the `OauthException`s thrown by the SDK.

Resolves USRLD-1006.

## Documentation

Does this require changes to the WorkOS Docs? E.g. the [API
Reference](https://workos.com/docs/reference) or code snippets need
updates.

```
[ ] Yes
```

If yes, link a related docs PR and add a docs maintainer as a reviewer.
Their approval is required.
