Wagtail 6.3 upgrade question about insert_editor_css hook

In our app we have the following two wagtail hooks

@hooks.register('insert_editor_css')
def editor_css():
    return format_html(
        '<link rel="stylesheet" href="{}">', static('domestic-editor.css'),
    )


@hooks.register('insert_global_admin_css')
def global_admin_css():
    env_stylesheet = ''

    if getattr(settings, 'ENVIRONMENT_CSS_THEME_FILE'):
        env_stylesheet = format_html(
            '<link rel="stylesheet" href="{}">',  # noqa: P103
            static(settings.ENVIRONMENT_CSS_THEME_FILE),
        )

    return (
        format_html(
            '<link rel="stylesheet" href="{}">', static('cms-admin/css/domestic.css'),
        )
    ) + env_stylesheet

However the insert_editor_css hook has been removed in Wagtail 6.x.x

How can we now add the code for just Edit pages as before

From Wagtail 4.0 onward, CSS inserted through the insert_editor_css hook was added to all admin pages, not just edit pages. It is therefore functionally identical to the insert_global_admin_css hook, and can be moved to a insert_global_admin_css hook with no change in behaviour.
