[README] Update README - install

[mvolonnino]

This is not really an issue but just wanted to make it aware in case anyone else i having the same issues I faced, or if they are migrating from utilizing eas-updates to codepush

Make sure to completely remove the expo-updates package from package.json if you utilized that before integrating this codepush plugin There will be no warnings or anything like that and everything will seem to work as intended.

I was running into two specific issues:

• iOS: everything worked as expected, and would download and even install the update correctly. But upon a force quit, the app would rollback and the codepush bundle would no longer be shown, but rather the bundle that was downloaded along with the App itself.

• Android: was getting the error below and it would never even fully download/install the bundle at all (codePush.sync() would not work either, or using codePush.checkForUpdates() and downloading manually would not work either)

  'Update is invalid - a JS bundle file named "null" could not be found within the downloaded contents'

---

After completely remove the expo-updates with

yarn remove expo-updates

and removing the below code from the app.json, then this plugin worked correctly and I have no issues on iOS or android this had to deal with hooking up eas updates and completely removing that along with removing package seems to have work

// filename: app.json

{
  "expo": {
       //...
       updates: {}, // remove this
}

Huge shoutout to @GSTJ for creating this plugin and to @mgscreativa for helping debug as well and finding the solution to those issues I was running into above.
