add missing season data to db

[FoxLisk]

currently we have Season 1 data all external to our db, as well as some seasons' overflow brackets. it would be nice to get that history into our db

maybe a good time to fix season.format as well - make it into 2 fields, like "chronological_id" and "title," or else re-id everything so we can use season.id semantically, and change the "format" values to the actual format.

Adding some more things that could be backfilled from a message in discord:

• Season number and lttp category format: (I think this is already done)
• Season description: Each season on the history page has a short description. Would be nice to pull that from the DB.
• Season dates: The month and year each season happened
• Previous race vods that would need to be manually backfilled: A thread in the dev discord with all the restream links we've captured so far
• Donation info: Something to showcase on season history for how much was donated to which charities. Maybe also shouting out the people who helped contribute and shouting out the winners that chose those charities
  • Additionally, donation info could show up under a separate heading on the player-detail page, below the Race History section
