Make sure the sitemap works properly with i18n #113
Description
The Spanish pages should be listed in the sitemap but we should make sure that whatever you are supposed to do to correctly list en/es pages in the site map is happening.
p.s. the sitemap doesn't generate in dev mode locally with npm run develop so you have to run npm run build to get a production build instead, or if you have a PR the netlify preview will have it.
