Remove deprecated networks when creating a forked ganache instance

[kevinbluer]

When creating a forked Ganache instance (Create new network | Ganache service | Fork) the following are returned:

Given Ropsten, Kovan, and Rinkeby are now deprecated we should remove them.

EDIT - We should also add the Sepolia testnet.

This might warrant a separate issue but we'll also need to address on the Infura returned networks too:

I have had a look at this and it appears the list for the Infura section at least, is coming directly from the API calls.

I think we will need to ask Infura about updating the API on their end or moving/upgrading our API calls to a newer API version.

Code is changed our side, need to confirm that sepolia forking is working correctly into ganache from the extension.

ok I have fixed the requirements page as part of this too.

Requirements are now driven from our constants correctly, stopping duplication of values/mismatches on the HTML page.
