Support for React 18

[kolban-google]

I tried to install react-json-tree on my React 18 environment and it failed. Do we have plans for a React 18 release?

$ npm i react-json-tree

Hi @kolban-google,

Have you tried to change the react-json-tree peer dependencies using patch-package?

  "peerDependencies": {
-   "@types/react": "^16.3.0 || ^17.0.0",
-    "react": "^16.3.0 || ^17.0.0"
+   "@types/react": "^16.3.0 || ^17.0.0  || ^18.0.0",
+   "react": "^16.3.0 || ^17.0.0  || ^18.0.0"
  }

Can you please report if it works?

@Methuselah96 we should consider a gradual migration to functional components and add react-18 as peer dependency.
We could start from smaller libs: react-json-tree for instance :).

Yeah, I was hoping to upgrade the devDependencies to React 18 at the same time here, but there's still a few packages that we depend on with old peerDependencies. I'll create a PR to just update the peerDependencies for now.
