misc(v2): better dx: yarn clear, yarn watch, yarn serve

[slorber]

• yarn clean: cleanup of useful folders (ts incremental build, babel cache, /lib...)

• yarn watch: start incremental TS compiltation in --watch mode over the whole project

• yarn serve: use serve to serve a production build of the project

I tried to create a watchPlugin on the website, because I don't like constantly restarting the site, but I don't think it's possible to live-update the plugins' code at runtime :(

---

The watch mode, even without hot code reload, could be useful. We could watch all packages, and only need to run yarn start:v2 to restart the site, instead of yarn start that will recompile each package. The developer feedback would be faster.

@yangshun @lex111 what do you think of including docusaurus clear and docusaurus serve commands?

I think it could be useful for other users as well.

@yangshun I think it's complicated to hot reload the D2 code, tried to hack a bit with nodejs child processes / spawn etc but it's not easy.

Found a solution to automatically restart the server. It's probably not the fastest DX we could get as each restart takes a few seconds, but it's still better than current DX and is a tiny change so could do the job for now:

    "start:v2:watch": "nodemon --watch \"./packages/*/lib/**/*.*\" --exec \"yarn start:v2\"",
