Remove pythonic int * list behavior (#10292)

# Description
The pythonism that multiplying a scalar integer with a list results in a
repeated concatenation of the list, is ambiguous with other possible
interpretations and thus actively harmful to clear semantics in nushell.

Another possible reading of this scalar/vector product would be trying
to perform elementwise multiplication with the scalar.

Before we bless this alternative as a more reasonable design the best
course of action is to remove this pythonism.

# User-Facing Changes
Breaking change as this turns `int * list` or `list * int` into hard
errors.
