Non cmd shells need their arguments escaped

[xt0rted]

cmd doesn't need to be quoted, but sh, pwsh, etc. do and they also need to be escaped😳

dotnet-run-script/src/RunScriptCommand.cs

Lines 117 to 120 in 9f1110c

	process.StartInfo.Arguments =
	isCmd
	? $"/d /s /c {toExecute}"
	: $"-c \"{toExecute}\"";

This should be fixed and published ahead of #10.
