Update side_panels.py

[aekong]

The most recent release of wagtail 5.2 replaces PagePreviewSidePanel with PreviewSidePanel.

wagtail_localize/side_panels.py needs a small update to comply

Hi! I'm using your changes in wagtail-localize module for the Wagtail 5.2 upgrade. It works, but there are issues/bugs within the LocalizedPageSidePanels class.

The __init__ method arguments in the base class are changed. This may affect other classes as well.

class LocalizedPageSidePanels(PageStatusSidePanel):
    def __init__(self, request, page, translation):
        super().__init__(
            # - order of page & request arguments are changed.
            page,
            request,
            # - these arguments are removed
            # preview_enabled=False,
            #comments_enabled=False,
            #show_schedule_publishing_toggle=False,
        )

If i try to translate an existing page, i get this following error message:

In template /usr/local/lib/python3.12/site-packages/wagtail/admin/templates/wagtailadmin/shared/side_panel_toggles.html, error at line 3

'LocalizedPageSidePanels' object is not iterable

{% load wagtailadmin_tags %} 
{% for panel in side_panels %}
    {% component panel.toggle %}
{% endfor %}

Many thanks for addressing these issues. Kind regards.
