Fix terminal color on Windows

[Dreeam-qwq]

Windows doesn't have environment variables TERM and COLORTERM by default, but we assuming that it supports the truecolor for terminal.

Welcome to test it on:

• Java 21 and Java 22

and,

• Windows, Linux, Pterodactyl panel or MSCM panel.

Things to test:

• Whether has color
• Whether can input words/commands in console smoothly
• Whether has Console formatting is broken in Pterodactyl #73 issue on panel (Don't add -Dterminal.jline=false and -Dterminal.ansi=true)

Test Jar: Leaf 1.21.1.zip

Tested on my side that all can work fine.
