Provide a Insta Before/After of Meteor 2 with React and then in Meteor 3

[filipenevola]

We want a guide showing how to migrate from Meteor 2 to Meteor 3 using React.

The main goal is to document for everybody to see and understand these changes case by case, for example, how to subscribe and fetch data in the client.

Also, as a side-effect, we can find potential issues in alpha versions of Meteor 3.

As an inspiration we could do something like this guy is doing to teach nextjs

The structure we imagine is something like this:

Title of Use case 1

Description

Code example in Meteor 2

Code example in Meteor 3

Details

If necessary, some additional explanation about the differences

---

Title of Use case 2

This makes no sense anymore.

Maybe a set up file for Cursor? We will get back to this later. Closing for now.
