chore: standardize on cruet for case conversion

`cruet` supports both conversion to `camelCase`/`PascalCase`/etc and
pluralization, while `convert_case` only supports case conversion.

`48ac1378` introduced `cruet` in psl. This comit makes
`mongodb-schema-connector` use `cruet` as well for consistency across
the codebase.
