Error: × Unsupported shell: Fish(Fish)Issue description
I came across a few issues trying pixi in a MSYS2 environment on windows with fish, notably, pixi shell fails saying Unsupported shell: Fish(Fish). However, pixi shell-hook actually works fine and outputs this:

end However, there are problems with this output:
- The first line is
set -gx Path ...while it should beset -gx PATHsince it's case-sensitive. - The path is using windows-style paths instead of linux-style (
cygpath) ones. - The path is separated by semicolons instead of being a fish array.
In the output of pixi shell-hook -s bash, PATH is correctly capitalized and uses linux-style paths:
export PATH="/d/home/user/git/pixi-project/.pixi/envs/default:/d/home/user/git/pixi-project/.pixi/envs/default/Library/mingw-w64/bin:/d/home/user/git/pixi-project/.pixi/envs/default/Library/usr/bin:/d/home/user/git/pixi-project/.pixi/envs/default/Library/bin:/d/home/user/git/pixi-project/.pixi/envs/default/Scripts:/d/home/user/git/pixi-project/.pixi/envs/default/bin:/d/home/user/.local/bin:/d/home/user/bin:/mingw64/bin:/usr/local/bin:/usr/bin:/usr/bin:/mingw64/bin:/usr/bin"

pixi shell working on fish in MSYS2.
Things work fine if I run set -gx PATH (string split ';' $Path | while read -l item; cygpath $item; end) to correct the PATH based on Path.
