[Feature Request] Add displayed champion on profile to PlayerClientPreferences in the lol-challenges-v1 API

[DarkIntaqt]

Since the challenges-v1 API is apparently responsible for serving a players profile preferences, such as bannerAccent, displayed challenges, title and the profile icon border (or ranked crest), I would love to get the displayed splash image of the champion (ideally with a skin Id) on a players profile page as well.

As seen on this image, the green areas cover data that we already have, while the red area is not available through the public api. (I really hope the person reading this is not color blind, if so: I am sorry, I can't edit the image anymore). The white crosses are data that are either a) not relevant or b) probably more relevant for the clash API.

By having this kind of data we could create a more personalized experience for a users profile.
The concern that by that way we know that an account has xyz skin is valid, however is this kind of data publicly accessible through the summoner search in the client as well.
