Fix ModifierThreshold upper tag

[avtobus32]

Fixes # .

Description of the problem being solved:

MultiplierThreshold with "upper=true" was applied only if value exact match threshold, while it should use threshould as upper limit
I have experienced this with mod "Projectiles have 40% increased Critical Damage Bonus against Enemies within 2m" that should apply whenever the distance is <= 20 units, but was applied only when distance is exactly 20units

Steps taken to verify a working solution:

• Removed "and tag.exact" check that i couldnt find any reference to, and i believe it is dev/testing product of Adding support for Uhtred's Augury / Exodus / Omen: bbffdae
