docs: migrate Docusaurus to v2

[Croftyland]

Summary

Migration from v1 to v2

Test plan

Hi, @yangshun, please check react native testing library as an example of resolved issue "migrate react native testing library to v2 #226 "

[Croftyland]

@brooksbecton I couldn't understand what you have done

[Croftyland]

@thymikee all your comments were done

Please, @thymikee, @yangshun check

[lex111]

@Croftyland why did you remove Docker? Please bring it back, and just delete the removed paths in Docker files.

[Croftyland]

@lex111, is anything else ok?

[endiliey]

You might want to deploy it somewhere (eg: netlify or now) for live demo

[yangshun]

Good work on the migration! Try to understand what each section of the code is doing as I see quite a bit of remnants from v1 which aren't relevant to v2.

Let's also try to get a demo running.

@yangshun everything has fixed

[yangshun]

@thymikee please review again 😄

[thymikee]

cc @lex111 for another review. I'll check it myself soon

[lex111]

Unfortunately, there are many conversations/suggestions marked as resolved, but not actually fixed :(

[thymikee]

@Croftyland would you be able to address them? 🙂

[yangshun]

@Croftyland friendly ping :) Let us know if you need help and we can help out with the last few items

[Croftyland]

I can't guess what's wrong with footer if we don't need it

Anything else is fixed, please check

[thymikee]

We're following up on this topic here: #299. Sorry it took so long, but Docusaurus grew a lot better since this PR started and adopted some users, like React Navigation. I hope to merge the migration in a few days :)

Thank you very much for your work ❤️
