* This fixes issues 11383.
The introduction of the new Examine library caused an unintended consequence that it stopped indexing of nodes with language variants on them when one of the variants was unpublished.
These changes align ValueSetValidationStatus.Filtered to indicate that a node is intended as filtered out of a search, not that parts of its contents had been excluded from the result.
This brings it inline with how it is used in Umbraco.Examine.Lucene/UmbracoContentIndex
Unit tests changed to indicate the intent of ValueSetValidationStatus.Filtered
Change to UmbracoViewPage to make model variable nullable (because the solution wouldn't build otherwise on 2022)
* revert to use explicit type instead of var
