Document adding ./cypress.config.ts to tsconfig.exclude to avoid conflicts with Jest

Description

We should update the Cypress Types Conflict with Jest section of the docs to reflect the solution outlined here by @ZachJW34 to the issue reported in cypress-io/cypress#22059.

It's also been suggested in that issue to surface this in the migration guide, which I think is not a bad idea.

I'm creating this issue in the docs so that we can close the issue in the main repo and add the information to our main docs.

Hello,

Just to clarify, it's not only on Jest, we have the same problem on Angular with Jasmine, the fix works the same.
