League: Seasons

Create a league season

Creates an upcoming season for a league game. Requires a personal or developer API key whose owner is currently a league ADMIN of the league in the path, with the league seasons capability enabled on the key. League API access is gated at api_pro on the league owner's plan. Supply an optional Idempotency-Key request header to make retries safe: an identical key and body replays the original season id, while the same key with a different body returns 409 error_idempotency_key_conflict.
