docs: explain split aces in the blackjack help book

[JustinasLa]

Summary

• Adds a "Splitting aces" page after the Split page of the blackjack help book: split aces take a single card each and are then done, and an ace with a ten after a split pays even money, not 3 to 2.

Why

A player split aces, got 21 on one, and reported that the game never asked about the other hand. That is the intended rule (advancePlay ends split aces after one card), but nothing in game explained it.

The related window where a player could still hit a hand showing 21 is already closed on main (#24) and shipped in v0.3.3.

Notes

• help.yml is only copied out when missing, so the live plugins/Games/help.yml on each server needs the same page added by hand followed by /games reload.
• The YAML parses (16 blackjack pages). Maven could not run locally because the private dependency jars are missing, so CI is the test run.

📝 Summary

Summary by CodeRabbit

• Documentation
  • Added a Blackjack help page explaining that split aces each receive one card and then stand. It also notes that aces can be split again when the table permits and hands are available, and that a split ace receiving a ten-valued card makes 21, paid at even money rather than as blackjack.

Walkthrough

The Blackjack help content describes the one-card limit for each split ace, conditions for splitting aces again, and the even-money payout when a split ace receives a ten.
