Non-existent sitemaps are loaded

[ojdo]

Reproduction steps

Visit any current site using this plugin, e.g. https://ultrabug.github.io/mkdocs-static-i18n/.

Expected behavior

• Only existing sitemaps are queried, no errors in the browser console.

Observed behavior

• Browser console reveals that a non-existent https://ultrabug.github.io/mkdocs-static-i18n/fr/sitemap.xml attempted to be loaded (404)

So far, I have traced this back to mkdocs-material's setupAlternate iteration that tries to retrieve one sitemap per rel="alternate" declared link in the header.

<link rel="alternate" href="/mkdocs-static-i18n/" hreflang="en">
<link rel="alternate" href="/mkdocs-static-i18n/fr/" hreflang="fr">

I am reporting this here as I assume that the reconfigure material logic here needs a slight update to prevent this.

I could provide an MR if provided with some guidance whether it makes sense to fix this here, or whether the mkdocs-material theme (which unfortunately has gone into maintenance mode) needs to change its ways.

Hi,

Same issue here : just disable "reconfigure_material" and the issue go away, but you lose the language switcher.

Help pls !
