Now the default behaviour for switching the chain is actually to try to add it, if it already exists, we're getting a prompt to switch to it.

This solves a HUGE UX issue we have with our current SDK. With this PR users are getting the nice prompt to add and or/ switch to the chain that's installed on their wallets.
@juans-chainsafe to test: change the network in project settings to OP Sepolia testnet or any other you prefer.
Make sure you don't have that network in your wallet.
Closes #1231

I'm trying in iOS and is not working, it tries to switch the network and add it, but I get a error:

[Web3] Failed to add and switch to the network: {"code":-32603,"message":"Request for method 'eth_chainId on https://goerli.optimism.io failed","data":{"networkErr":{}}}
ChainSafe.Gaming.Evm.Unity.<ActionWrapper>d__13:MoveNext()
UnityEngine.SetupCoroutine:InvokeMoveNext(IEnumerator, IntPtr)
ChainSafe.Gaming.Evm.Unity.Dispatcher:Update()

It switched to Metamask to add the network (I guess?) but nothing happen there, when I switched back to the Unity app, I got the error.

Steps

1. Added Optimism Goerli network (because I don't have it in Metamask)
   

2. Build in iOS

3. Connect with Reown and Metamask

4. Sign message in Metamask and go back to Unity app

5. Message of "Switching network" appears and redirects me to Metamask

6. Nothing happens in Metamask, so I switch back to the app

My bad, Optimism Goerli is deprecated so is expected to fail.

I retried with Avalanche Fuji and is working! It added the network to my Metamask account and then switched to that network.

I also tried #1201 and is working, so we can close that issue after this gets merged.

Nice improvement for Reown! Left a couple of questions and suggestions.
