Review React Guide

[D4nte]

When following https://docs.wakuconnect.dev/docs/guides/07_reactjs_relay/ with [email protected] I noticed that I only needed to install assert for the example to work:

• cra-webpack-rewired and overriding the webpack config are not needed
• No other polyfills are needed

The polyfills might only be needed when using specific modules (ie, Buffer might be used only for the cryptography).

We should better understand and document the polyfill needs, especially if it makes the library easier to use.

Note assert was removed: #740

To be done when documenting @waku/core as part of #802.

Was this completed during #802 @fryorcraken ? And can it be closed

Just came across this when looking for a good first issue

Closing this as all guides need to be reviewed.
Work to be planned.
