Migrate SSO to camelCased (#793)

## Description

* Part of a wider initiative to migrate our Node SDK to camel case for
the 3.0.0 release.
* Migrates the Single Sign-On module to camel case.

## 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.
