Fix go.mod

[Ferret-san]

Ever since some recent commits, attempting to run go mod tidy on Rollkit would results in the following error:

github.com/rollkit/rollkit/block imports
	github.com/cometbft/cometbft/abci/types imports
	github.com/cometbft/cometbft/crypto/secp256k1 imports
	github.com/btcsuite/btcd/btcec/v2/ecdsa tested by
	github.com/btcsuite/btcd/btcec/v2/ecdsa.test imports
	github.com/btcsuite/btcd/chaincfg/chainhash: ambiguous import: found package github.com/btcsuite/btcd/chaincfg/chainhash in multiple modules:
	github.com/btcsuite/btcd v0.22.0-beta (/home/dferrer/go/pkg/mod/github.com/btcsuite/btcd@v0.22.0-beta/chaincfg/chainhash)
	github.com/btcsuite/btcd/chaincfg/chainhash v1.0.1 (/home/dferrer/go/pkg/mod/github.com/btcsuite/btcd/chaincfg/chainhash@v1.0.1)

This PR fixes the ambiguous import issue by upgrading github.com/btcsuite/btcd/chaincfg/chainhash v1.0.1 => v1.0.2
