[MoM] change Inferno Grenade fuse

Summary

Bugfixes "[MoM] change Inferno Grenade fuse and casing"

Purpose of change

The Inferno Grenade recipe uses the delayed fuze for its recipe. This doesn't make sense to me, because the delayed fuze is a complicated mechanical assembly that can only be acquired by disassembling military explosives, whereas the inferno grenade is clearly an improvised explosive made from duct tape and tin cans. Also, the delayed fuze says its purpose is to directly detonate stable explosives, but the inferno grenade uses volatile explosives to catalyze its psychic firestorm, much more akin to the way e.g. the homemade grenades use volatile explosives to catalyze stable explosives, and those use standard fuses.

e: also, inferno grenades are the size of small homemade grenades and drop empty canisters when used, so they should probably use the casings for small grenades rather than medium tin can in their recipe

Describe the solution

Change it to the standard "fuse" item.

e: change it to use the small_grenade_case list instead of medium tin can

Describe alternatives you've considered

I was gonna ask @Standing-Storm if this was intentional, but it's such a quick change it was easier to just make the PR and let them shoot it down if necessary.

Maybe also some alternatives for tin cans...

Oh right, I forgot about that. Inferno grenades are the size of small homemade grenades and drop "empty canister" when used, so they should probably use the small grenade casings in the the recipe rather than the medium tin can. I've now included that change as well
