Duplicate fetch dependencies across WalletConnect SDK

[v1rtl]

Describe the bug

WalletConnect dependency tree includes 5 different, but identical fetch implementations instead of using just one:

• [email protected]
• [email protected]
• [email protected]
• [email protected]
• [email protected]

This bloats up the bundle size and polyfills existing fetch implementation that all major platforms already support. The only platform without fetch API is IE11, in which case people who need to support IE11 can set up the polyfill themselves through webpack or any other bundler they're using. And from what I know, WalletConnect doesn't work on IE11.

Node.js supports fetch since v18, which is 2 years old. React Native has native fetch support. Deno and Bun natively implement fetch. All browsers except IE implement fetch since very long ago.

SDK Version (if relevant)

• Client: TypeScript
• Version [e.g. 22] 2.13.3

To Reproduce Steps to reproduce the behavior:

1. npm i @walletconnect/ethereum-provider
2. Get 5 different fetch implementations downloaded

Expected behavior

Either only one fetch implementation to be used, or preferably use native one.
