Support react 17

[Bajdzis]

Currently, if we install the docz, we will get an error:

npm ERR! code ERESOLVE
npm ERR! ERESOLVE unable to resolve dependency tree
npm ERR! 
npm ERR! While resolving: test@1.0.0
npm ERR! Found: react@17.0.2

For those who encounter the error and don't know how to proceed, the temp fix is to bypass the peer installation effort:

npm install docz --save --legacy-peer-deps

This tells the installer to ignore trying to install an older version of react and react-dom on top of the recent version your project has.

But it's likely you're running a later version of Node as well, so this issue will probably be the next thing you'd have to look at: "ERR_REQUIRE_ESM error on start" #1674
