feat: fake metamask wallet detection

[EdouardBougon]

I’ve discovered an issue with the SDK (pure JavaScript and wagmi). The SDK tests the boolean window.ethereum.isMetaMask to detect if the extension is installed. However, some other extensions use the same boolean to imitate MetaMask (e.g., Uniswap, Zerion, Rabby, etc.), and it works…

So, if the MetaMask extension is not installed, but one of those wallets is, the SDK will open the “fake” extension instead of the connection modal. Wagmi has a similar detection on their side, but they don’t take into account the “Uniswap Wallet.”

I also created a PR on Wagmi to add Uniswap to their detection test.

Here’s a demo video.
