LGTM -- no need for package authoring as this only ships in framework.

Backport of #65569 to release/6.0
/cc @eiriktsarpalis
Customer Impact
Addresses a customer reported regression from .NET 5 (#65419). The inclusion of new
FirstOrDefault/SingleOrDefault/LastOrDefaultoverloads in .NET 6 has surfaced a bug in our Queryable-to-Enumerable method mapping logic in System.Linq.Queryable.Testing
Added unit tests verifying that the regression no longer occurs.
Risk
Low to moderate. Updates the product code to account for the corner case introduced by the new overloads.
