In ##41788, the `disambiguateDocsPathsProcessor` was introduced to fix
an issue with case-insensitively equal paths. This processor may alter
the paths of some docs and thus their final URL in the app.
Previously, both the `disambiguateDocPathsProcessor` and the
`createSitemap` processor (which relies on the docs' computed paths to
generate the sitemap file) were configured to run before the
"rendering-docs" phase. However, this resulted in the
`disambiguateDocPathsProcessor`'s running after `createSitemap`, which
meant that the sitemap did not include the updated doc paths.
This commit fixes it by ensuring that the
`disambiguateDocPathsProcessor` is explicitly run before the
`createSitemap` processor, so that the latter will be able to take into
account any changes made by the former.
