Add Windows Terminal Support

[louisefindlay23]

Be able to change the default terminal of Brackets-Git to Windows Terminal.

Whenever I change the custom terminal command in Git Settings to wt (or wt.exe) and reload Brackets, it automatically resets to Git Bash. I've altered terminal.sh to add an elif for wt but the settings still resets to Git Bash after reloading.

100% agree, needs full terminal support with windows based systems (x64).
