Stop including page.scss in the cockpit-components-dialog.scss
Stop including page.scss in the cockpit-components-dialog.scss

This file is supposed to be imported by each page, including it here
makes this stylesheet get duplicated in the resulting css file for all
page which use this dialog implementation.

Note: 964121ec2c44d016ca3a52e7d2276f05401b940d@import is that the relevant file is only
imported once, no matter how many times you @use it in a project.
Of course this did not work here, ad the cockpit-components-dialog.scss
is imported directly from the jsx.
