fix: cp-7.51.0 missing explorer url in bridge tx

[stanleyyconsensys]

Description

This PR is fixed the block explorer URL doesnt not return correctly for bridge transaction

it is because the previous method is heavy depends on etherscan-link to get the URL

on the other hand, if the hashmap of network <> block explorer url is not up to date, there will be an issue (it only support 0x1)

In this fix, we copy the same behavior with app/components/hooks/useBlockExplorer.ts to have minimal change to fix the issue
