Update supported devEngines

[eps1lon]

Summary

Change devEngines to indicate the required node version to perform every development workflow.

With node@12.16.0 yarn build react-server-dom-webpack/node-loader throws with

$ node ./scripts/rollup/build.js react-server-dom-webpack/node-loader
/home/eps1lon/Development/forks/react/scripts/rollup/build.js:44
  throw err;
  ^

Error: Cannot find module 'react-server-dom-webpack/node-loader'

error Command failed with exit code 1.

Probably because of the way exports field in packages/react-server-dom-webpack/package.json is constructed.

"exports": {
    ".": "./index.js",
    "./plugin": "./plugin.js",
    "./writer": {
      "react-server": {
        "node": "./writer.node.server.js",
        "browser": "./writer.browser.server.js"
      },
      "default": "./writer.js"
    },
    "./writer.node.server": "./writer.node.server.js",
    "./writer.browser.server": "./writer.browser.server.js",
    "./node-loader": "./esm/react-server-dom-webpack-node-loader.js",
    "./node-register": "./node-register.js",
    "./package.json": "./package.json"
  },

With node@12.17.0 the command passes.

Test Plan

• CI green
• yarn build react-server-dom-webpack/node-loader passes in node@12.17.0 and node@16.0.0

The Code Sandbox documentation says:

  // Node.js version to use for building the PR.
  // Supported versions are '10' (10.23.0, default), '12' (12.20.0) and '14' (14.15.1).
  "node": "14"

And CI is failing with an error message that says:

AssertionError [ERR_ASSERTION]: Current node version is not supported for development, expected "10.23.0" to satisfy "^12.17.0 || 13.x || 14.x || 15.x || 16.x".

Which suggests to me that we should update the .codesandbox/ci.json config file to override the default of Node 10 with either 12 or 14, e.g.:

  "node": "14"

Good point. I went with the lowest possible version that's also being used in CI.
