Fixes BX-####
Figma link (if any):

What changed (plus any additional context for devs)

• window.ethereum.providers causing infinite loop with Rainbow wallet when having Coinbase and MetaMask installed. This is causing a memory leak due to window.ethereum.providers overrides.

EDIT:
This is a small improvement from previous fix we did

This PR is an alternative to #1613 (review)

@magiziz Esteban's PR includes a isMetaMask = false now for the EIP-6963 announcer. Does that accomplish the same thing as this PR?

[magiziz]

@DanielSinclair Yes, that's correct. Instead we delete the isMetaMask property and bring back the walletRouter and window.ethereum.providers. Also the Wagmi team suggested that EIP-6963 and EIP-1193 should share the same instance rather than copying them. This is because, currently, in RainbowKit, you're getting two connections due to them not being the same instance. Here is the code which you can look at https://github.com/wevm/wagmi/blob/main/packages/core/src/actions/reconnect.ts#L71-L75

This is not a major change, but it's a small improvement.

Seems like e2e test fails because we use this e2e app https://bx-e2e-dapp.vercel.app. It requires isMetaMask to be true.
