[i18n] Bad URL in a sitemap that mixes FR + ES

Issue with the sitemap in Victoire

Here is an example of the problem I met with Victoire on a project.
Given I have the following I18n page:

• 🇫🇷 information-pratiques
• 🇪🇸 informacion-practica

And a the following page:

• 🇫🇷 information-pratiques/saint-pierre-et-miquelon

Then the sitemap turns crazy and show a french and spanish mixed hybrid url :

This can be problematic because bots like Google follow these links, trigger some 404 and could think that the website is not relevant.
