Game code metadata should match that of Lichess.org

[Naviary2]

Currently the game's ICN's, or game code's, metadata is different from that of Lichess.org (scroll down to "Sample"). If we want to be consistent with norms, we should probably convert!

An example of the metadata of an ICN (Infinite Chess Notation) metadata now is:

[Variant: Knighted Chess]
[White: Owner]
[Black: aaa]
[Clock: 10+4]
[Date: 2024/07/22 05:42:12]
[Result: 0-1]
[Condition: Resignation]
[Rated: No]

An example of Lichess's metadata is:

[Event "Rated Bullet tournament https://lichess.org/tournament/yc1WW2Ox"]
[Site "https://lichess.org/PpwPOZMq"]
[Date "2017.04.01"]
[Round "-"]
[White "Abbot"]
[Black "Costello"]
[Result "0-1"]
[UTCDate "2017.04.01"]
[UTCTime "11:32:01"]
[WhiteElo "2100"]
[BlackElo "2000"]
[WhiteRatingDiff "-4"]
[BlackRatingDiff "+1"]
[WhiteTitle "FM"]
[ECO "B30"]
[Opening "Sicilian Defense: Old Sicilian"]
[TimeControl "300+0"]
[Termination "Time forfeit"]

Some of these aren't relevant to us yet, but there are others which match metadata we have now.

I can take care of updating formatconverter.js from outputting [MetadataName: value] to outputting [MetadataName "value"] since I wrote it.

I have resolved this. We now adopt most of these norms!
