Support map redirects for sites using deprecated Google Maps JavaScript API v2
As found on e.g. https://ipres2022.scot/, there are still sites using the old long since deprecated Maps JS API v2 as the iframe src, which redirects to a Embed API URL when specified in the output query parameter (here: https://maps.google.com/maps?q=99%20George%20St%2C%20Glasgow%20G1%201RD&t=m&z=14&output=embed&iwloc=near).
Maybe support for this form could be added to the maps helpers for better backwards compatibility. As is this triggers the fallback handling and tries to use the /search path for OpenStreetMap which doesn't work as www.openstreetmap.org/search currently returns a x-frame-options: sameorigin header. Also the base URL for OpenStreetMap should be changed to include the www to save an unnecessary redirect.
But in this page it's saying that it will no longer be working as of May 26, 2021, what?!
