fix(parser): optional targeting for "attach any number of target" trigger (Super-Soldier Serum)

[matthewevans]

"Whenever enchanted creature attacks or blocks, attach any number of target
Equipment you control to it" forced a mandatory Equipment target, softlocking
when every Equipment was already attached (no way to decline).

The trigger lowering only surfaced optional_targeting when the body contained
the literal "up to one"; extend the detector to "any number of target" so
the variable-count-down-to-zero target (CR 601.2c) yields an optional slot and
a decline action.
