feat: upgrade react-native-webview (#7759)

## **Description**

Moving away from `.patch` changes on the webview

Our [RNWebView
fork](https://github.com/MetaMask/react-native-webview-mm) contains the
security patches.
The "Javascript Injection" patch was removed and the related patches to
fix bugs introduced by that.

Jest snapshots updates to reflect the new RNWebView component
