Experiment with light-client in docusaurus

[jeluard]

Using light-client with docusaurus triggers a number of errors. While it might be doable to tweak webpack configuration to overcome those, it looks worth looking at tackling those individually to improve end-user experience.

What can be done

• bls (crypto in blst-native); should not be used, might require conditional exports
• blst (crypto, ls, path in script); same as previous
• bls-eth-wasm (crypto); fixed by chore: upgrade node platforms bls#159
• eventsource (http, https) Reduce light-client dependency on api #6542

Errors

Module not found: Error: Can't resolve 'crypto' in '/Users/julien/Documents/Projects/jeluard/lodestar/docs/node_modules/bls-eth-wasm/src'
BREAKING CHANGE: webpack < 5 used to include polyfills for node.js core modules by default.
This is no longer the case. Verify if you need this module and configure a polyfill for it.

If you want to include a polyfill, you need to:
        - add a fallback 'resolve.fallback: { "crypto": require.resolve("crypto-browserify") }'
        - install 'crypto-browserify'
If you don't want to include a polyfill, you can use an empty module like this:
        resolve.fallback: { "crypto": false }
