* Fix ResourceQuantity parsing: reject strings with multiple decimal points

Fractions 8.x changed behavior so that Fraction.FromString("1.1.") no
longer throws but returns 11/100. Add explicit validation to reject
numeric parts containing more than one decimal point, preserving the
original behavior and fixing QuantityValueTests.Parse CI failure.
