Add e2e test and confirm support for datetime date list widget

I've tested it and it works well for me, test included.

The only issue I've found, that I guess only affects my environment and, even though, is not important as it's a test module is that I can't uninstall the module:

I'll let others to test in case they also have the same issue with the uninstall.

Note: I haven't reinstalled the site.

📌 Add e2e test and confirm support for date range date list widget Active

Rebased this off 0.x which includes a conflict free approach from 📌 Add e2e tests for telephone widget in page data form Active

Even if the test is passing, when I select a value the select box "clears". We should show the selected option.
I'm guessing this is caused by the change in 📌 Add e2e test and confirm support for date range date list widget Active , as @isholgueras reported this worked for him.

This was not catched on the tests. The select "clears" visually, but the data is stored and posted correctly, and after publishing and refreshing the page you can see the values you selected.

The cause is the options are casted as ints in parseValue at function-utils.js. when the values on the select are strings. It happens too in field_xbt_daterange_datelist.
Not sure how to fix this visually AND on the stored data, which requires ints. But hope this helps.
We would need some way to ensure in Cypress that the value selected is actually visible too. We are actually forcing the hidden select.

    // Radix renders these as a hidden element with a button to trigger, so
    // we have to use force.
    cy.get(`@${key}`).select(String(value), { force: true });

but we need to check the button label is changed too to the right value I guess?

LGTM!
