Fix priority assignment in sitemap generation

[john-gitbook]

Related to this ticket: https://linear.app/gitbook-x/issue/RND-8690/update-sitemap-to-fully-comply-with-xml-sitemap-protocol

Users are asking if we can update the sitemap to have 'priority' come after 'location'. In most cases this doesn't matter but for more strict crawlers the format needs to fully comply with xml sitemap protocol.
