Currently we're normalising custom element attribute keys from kebab-case to camelCase for overall ease of use and consistency with common code conventions. We aren't, however, doing the same for slot attribute values.
This PR addresses this, and allows a consumer to provide whichever common casing convention they'd like to a slot key value, and expect that casing to be normalised to camelCase.
