fix(subgraph): casting-fixes

[tractorss]

1. Kleros core

   • appears when Execute function is called and TokenAndEthShift event is fired.
   • stack :-handleTokenAndETHShift -> updatePenalty -> entities/Penalty.ts/line-9, jurorAddress not being casted to
     HexString, fixed that

2. Dispute Template

   • _templateTag is a indexed string , so it is being hashed(keccak256)
   • when handling in handleDisputeTemplate , toString is being used instead of toHexString(since it's a hash) to convert
     _templateTag

Cross checked the weird characters for both the subgraphs and confirmed the above.

For cross checking, these are the event logs https://goerli.arbiscan.io/tx/0x0f2b2c6a2b145f5e8889a262db0a3fb2ebb72566f924746d6a3819ff6e2380ac#eventlog
that were triggering the code and resulting in warnings
