This PR changes the ranked 1vs1 config to use the original format

(Reasoning in the discord thread)

But I still think we need a **1vs1 "party mode"**. With nations, ALL our
small maps, and sometimes compact maps. Maybe even sometimes with 5M
starting gold.
- Offering it to all 1vs1 players below a specific ELO count is probably
not the best idea: Some people will avoid getting too much ELO, others
will hate it until they have enough ELO.
- Offering another matchmaking queue might be an idea, but might cause
too much complexity (needs its own ELO system and its own leaderboard).
- A solution could be: Offer 1vs1 party games without ELO in the
upcoming new "special" rotation (Collect 20 players and put them into 10
games)
