Add tests to the app generated by create-react-admin with ra-data-fakerest

[djhi]

How To Test

make build-create-react-admin install

Then from outside the project monorepo, call:

[PATH TO MONOREPO]/node_modules/.bin/create-react-admin myadmin --data-provider ra-data-fakerest --auth-provider none --install npm
like:
./react-admin-next/node_modules/.bin/create-react-admin myadmin2 --data-provider ra-data-fakerest --auth-provider none --install npm

and run the tests:

cd myadmin
npm run test

I also have a few more important remarks.

I tested the 'published' version of the CLI (following the instructions in the Readme) and found out that:

1. Running npm install to install the build version of the CLI locally fails, because of the following error: Could not resolve dependency: peer react@"^16.5.2 || ^17.0.0" from ink-select-input@4.2.2 (since we now require react 18) => Do we need to update to a newer version of ink-select-input?
2. in the generated app, we have both a .gitignore and a gitignore file
3. the generated Readme does not explain how to run the tests
4. The test is failing in the generated project, because of a timeout (Test timed out in 5000ms) although the app is running properly locally 🤷‍♂️
5. The tests seem to assume we chose an authProvider, but it's not mandatory. We should only include the test if an authProvider was selected IMO

Code looks good, but:

• There is still a gitignore file generated in addition to .gitignore
• Tests are still failing when run in the generated project (timeout after 5000 ms)

FIxed

Not sure what happen on your machine. It works fine on mine and on the CI (#9580)

Okay so I pushed the investigation further

• Tests run fine with the parameter --auth-provider none
• Tests fail (on my machine) with the parameter --auth-provider local-auth-provider (timeout after 5000 ms)
• If I increase the test timeout to 6000 ms then it works

=> Hence I recommend increasing the timeout a bit by default, otherwise we risk having the test fail on the CI too 🤷
