chore: Remove special fix for plonk verifiers

[numtel]

iden3/snarkjs#464 was merged and is now included in snarkjs 0.7.5 so we can remove the special case for plonk verifiers:

The way snarkjs is set as a peerDependency for 0.7.x, it would need to be updated to ^0.7.5 too I would imagine though

good point!

indeed

will include this for some minor version update soon, but lets wait a bit until SnarkJS gets updated around the place 👍🏻

the existing fix does not break with the fixed snarksj version though right?
