Subject: [PATCH] Editor: Automatically apply global styles duotone filters to
 render in post editor.

Global styles duotone filters were not rendering in the post editor. This fixes that by adding `wp_global_styles_render_svg_filters` to the `in_admin_header` so it renders in the body before the editor.

Follow-up [52757].

Props ajlende, abhanonstopnewsuk.
Fixes #55190.
