useGetABI doesn't support ERC-1967-compliant proxy contracts

[0xMillz]

Problem:
Using WalletConnect with most proxy contracts fails with no matching function error

Suggested fix:
Add the 'implementation' method to this Set and handle it (it doesn't taking any args unlike getFunctionImplementation).

web/src/plugins/walletConnectToDapps/hooks/useGetAbi.tsx

Line 42 in 2e2aae1

const proxyFunctions = new Set(['getFunctionImplementation'])

Why it matters:
ERC-1967 with the implementation() method is the most commonly used way to get the ABI of the logic contract from a proxy contract.
