use the official testing-lib getSuggestedQuery for query advise

[smeijer]

Now that @testing-library/dom has adopted the query suggestions, and added it to its core, we can use the exported getSuggestedQuery method to ensure that we are on the same page as the official lib.

// getSuggestedQuery(...)
{
  queryName: 'Role',
  queryMethod: 'getByRole',
  queryArgs: ['button', { name: /submit/i }],
  variant: 'get',
  toString() // » getByRole('button', { name: /submit/i })
}

For this to work, we need to upgrade @testing-library/dom to 7.11.0 (or higher), to include the changes from testing-library/dom-testing-library#608
