RealFavicon API now returns different set of favicons

It looks like the RealFavicon API has changed (probably associated with this), because it no longer returns the same set of favicons. Of the hardcoded filenames in the BS5 template, only "apple-touch-icon.png" is still returned:

pkgdown/inst/BS5/templates/head.html

Lines 8 to 13 in 8d9cba1

	<link rel="icon" type="image/png" sizes="16x16" href="{{#site}}{{root}}{{/site}}favicon-16x16.png">
	<link rel="icon" type="image/png" sizes="32x32" href="{{#site}}{{root}}{{/site}}favicon-32x32.png">
	<link rel="apple-touch-icon" type="image/png" sizes="180x180" href="{{#site}}{{root}}{{/site}}apple-touch-icon.png" />
	<link rel="apple-touch-icon" type="image/png" sizes="120x120" href="{{#site}}{{root}}{{/site}}apple-touch-icon-120x120.png" />
	<link rel="apple-touch-icon" type="image/png" sizes="76x76" href="{{#site}}{{root}}{{/site}}apple-touch-icon-76x76.png" />
	<link rel="apple-touch-icon" type="image/png" sizes="60x60" href="{{#site}}{{root}}{{/site}}apple-touch-icon-60x60.png" />

This then causes the favicon to not render on some devices (e.g., Chrome/Edge on Windows). Here's the website I've recently built for my new R package as an example: https://williamgearty.com/deeptimedata. The list of favicons as built by build_favicons() can be seen here.
