Description of problem:

With ODC-5851 we introduced react-testing-library (or the "testing-library") to our code.

Most react examples also uses the "jest-dom" extensions (https://testing-library.com/docs/ecosystem-jest-dom/) which provides additional semantic assertions like

expect(...).toBeEnabled()
expect(...).toBeDisabled()
expect(...).toHaveValue(...)
expect(...).toHaveDescription(...)
expect(...).toBeChecked()

This makes our tese case easier to understand then... for example:

expect(element.getAttribute("disabled")).toEquals("disabled")
expect((element as HTMLInputElement).value)).toEquals(...)

To simplify our tests and make adopting the examples from the official website easier, we should also add the "jest-dom" extension.

:warning: The problem with just adding the library is that the typescript definition breaks jest autocompletion / type definition. For example:

expect("").to<tab> // doesn't show toEquals or toBeEnabled after installing the library!

Actual results:

1. react-testing-library jest-dom extension is not available

Expected results:

1. react-testing-library jest-dom should be available and tested with some of our react-testing-library tests (or a new one)
2. Autocompletion / Type definition of expect() should still work !!
