build.sh no longer works on macOS

[auduchinok]

Since #20080, build.sh does not longer work:

$ ./build.sh
/Users/eugene/Developer/fsharp//FSharp.slnx:
/Users/eugene/Developer/fsharp/eng/common/tools.sh: line 601: logger_switch[@]: unbound variable
Error building solution (exit code '1').

$ bash --version
GNU bash, version 3.2.57(1)-release (arm64-apple-darwin24)

That should probably go to arcade repo. Or local build.sh doesn't use arcade properly anymore.

Should be fixed on latest arcade, I will do the bump via a newer subscription (forcing every contributor to use net11 previews now)
