chore: remove _react and _vue selectors

[dgozman]

When querying with _react or _vue, suggest an alternative locator instead.

The error looks like this:

    Error: locator.click: Error: "_react" selector is not supported: locator('_react=BookList') resolved to 1 element:
        1) <ol>…</ol> aka getByText('Pride and PrejudiceTo Kill a')

    Call log:
      - waiting for locator('_react=BookList')
