revert eslint rule to disable requiring react in jsx scope

[terryttsai]

Description of the change

This PR reverts the configuration change made here

When we turn off react/react-in-jsx-scope, the eslint rule doesn't seem to stay off for some reason. If I start yarn dev in a new tab, usually we get no errors, but when modifying a file and recompiling, we start getting react/react-in-jsx-scope errors again. I'm at a loss as to why this is happening, and by now we've reimported React in most of our files to get around this issue.

So this PR just reinstates these rules.

Thanks @terryttsai ! This is indeed quite weird, but agreed that reverting is the way to go for now.
