Use json for players

[denniske]

I think json is easier to consume by clients than yaml, so I would like to change the players.yml to json. We can put the comments into a comment property like this:

- name: LaaaaaN
  country: es
  aoeelo: 62
  liquipedia: LaN
  esportsearnings: 56830
  aka:
    - LaN
  platforms:
    voobly:
      - "124116514" # ByT
      - "123989026" # Heresy
      - "124691590" # Jackie_Chan_
    rl:
      - "232410" # Antagonist
      - 196366-nac3 # Laaaaan
      - "1819193" # sheriff
      - "2602752"
      - "6892418"
  team: 21
  twitch:
    - https://www.twitch.tv/lan_aoe
  id: 8
  notability:
    aoe2: true
  discord_id: LaaaaaN#5576

YAML was chosen because it's easier to update as a human (since this file is maintained manually of course).
