Add Example Tests

If I put an e2e_examples folder in shrubs, I it will be in the shrubs folder in the support folder.

Is that weird? (maybe)

Will that break anything? (I don't think so as support commands don't run unless they're called.)

Some examples I am thinking of are the tests I've created for our recipes and Sitewide Alerts:

import {randNumber} from "@ngneat/falso";
describe('Check Drupal sitewide alerts.', () => {

  it('Input a new sitewide alert test.', () => {
    cy.login()
    cy.visit('/admin/content/sitewide_alert/add')

    // Set the alert title (text field).
    const alertName = 'Alert Title ' + randNumber()
    cy.get('#edit-name-0-value').clear().type(alertName)

    // Set the Alert type (select field).
    const alertStyle = 'Critical'
    cy.get('#edit-style').select(alertStyle)

    // Set the Alert message (wysiwyg field).
    const alertBannerMessage = 'Lorem ipsum dolor sit amet, consectetur adipiscing elit.'
    cy.ckeditorType('#edit-field-alert-banner-message-wrapper', alertBannerMessage).wait(500)

    // Save the new alert node.
    cy.get('#edit-submit').click()

    // Validation.

    // Check landing page node
    cy.wait(1000) // wait for the UI to catch up.

    // Verify new Alert is in the admin UI list of Alerts and click to edit.
    cy.get('a').contains(alertName).click()

    // Verify alert title.
    cy.get('#edit-name-0-value').should('have.value', alertName)

    // Verify alert style.
    cy.get('#edit-style').find(':selected').contains(alertStyle)

    // @TODO Verify alert message.
    // cy.get('.form-item--field-alert-banner-message-0-value .ck-editor__editable_inline p').should('have.value', alertBannerMessage)

    // Verify the alert is Active.
    cy.get('#edit-status-value').should('be.checked')
  })
})
