patch https://api.ottolearn.io/v1/rest/leaderboard()/contest()
Update the details of an existing Leaderboard's contest using a specific Leaderboard ID and Contest ID associated to it. Contest IDs associated to specific Leaderboard can be found using 'List Leaderboard Contest' API (/leaderboard({id}})/contest). Using this API call you can update the type of contest (draw or mostPoints), max winners, pointsRewardValue and contestRewardValue which are given to users on winning the contest and the contents. You can also add or update contest contents. Contest Results could not be created/updated directly using this API.
