Summary
As discussed in Chat, the modified on date for the sitemap is always set to the build time. This means that every entry is always seen as "updated" even though it hasn't been.
This is causing some issues in AI Search and is generally just not correct behaviour.
This updates it to using the Git modified on date and falling back to today if not possible
