Fsdk/Misc: workaround in FsxOnlyArguments

Filter out `preferreduilang` argument from script args in
FsxOnlyArguments() function. This argument started to appear
in .NET 10 when running .fsx scripts, breaking existing
scripts. It was then removed from fsi.CommandLineArgs, but not
from Environment.GetCommandLineArgs(), see [1]. Value
fsi.CommandLineArgs can't be used in the library, as it is
only available in fsx scripts.
