coverage for TS with CRA Component test example

**Is your feature request related to a problem? Please describe.**
One of the most exciting feature for cypress after 7.0 is the component testing feature. However I found it impossible to setup with CRA. I was able to get end to end testing working following examples in this repo, but there's no working example for component test ATM

**Describe the solution you'd like**
Would love to see an example with how to set up component test for typescript react projects created with CRA and it should generates coverage

**Describe alternatives you've considered**
Have to stick with jest and react-testing-library for now

**Additional context**
none
