Add external Wallet connectors (WalletConnect/RainbowKit) for project

[neutr0n420]

In the project we are natively using window.ethereum to do all the call on the smart contract. Instead of this we can use external Wallet providers like Wallet Connect and RainbowKit to add more information about the network we are using, also it enhance the User Experience as well.
Todo's

• Remove the support of window.Eth
• Install the SDK for Wallet Connect
• Implement it and make sure all the calls to the smart contract are going properly.
