[ENHANCEMENT] Add support for ENS on Sepolia

[benjisclowder]

What is this about?

Currently ENS is not supported on Sepolia and with further deprecation of Georli, ENS testing will be blocked due to Sepolia not supporting this.

Message that comes up when typing a valid ENS address at the moment: No address has been set for this name.

Scenario

• GIVEN a user is trying to send a transaction to a ENS address
• WHEN a user is typing the ENS address
• AND a user wants to proceed with the transaction
• THEN ENS address should be accepted

Design

No response

Technical Details

ENS support needs to be added on Sepolia due to deprecation of Goerli and lack of means to test the ENS feature in these conditions.

Threat Modeling Framework

This will help us further test the feature and prevent issues from being released in prod.

Hi, @benjisclowder I have added ENS support for Sepolia to the Metamask. The original author of ethereum-ens-network-map has not maintained their package anymore. We can help continue maintaining this package if you like.

Any action on this one? Seems very straightforward. Upon review of the ethereum-ens-network-map lib (as proposed in the PR) - it's so simple it could even just be imported somewhere and avoid the dependency. https://github.com/Opti-domains/ethereum-ens-network-map/blob/master/index.js
