Add full type name for Lucene lock type

[DrewScoggins]

In net9.0 the runtime now exposes it's own Lock type, dotnet/runtime#87672. This causes a build break as there is a collision between the Lucene type and the runtime type.

I added an alias for Lucene.Net.Store because that was colliding with OrchardCore.Search.Lucene. I am happy to do it another way if there is a better one, but this was what I came up with.

Does this change look good?

I think the change should be in lock only

[DrewScoggins]

If the change is limited to just the one that you requested you can't build the project and get this error

D:\git\OrchardCore\src\OrchardCore.Modules\OrchardCore.Search.Lucene\Services\LuceneIndexManager.cs(398,48): error CS02
34: The type or namespace name 'Net' does not exist in the namespace 'OrchardCore.Search.Lucene' (are you missing an as
sembly reference?) [D:\git\OrchardCore\src\OrchardCore.Modules\OrchardCore.Search.Lucene\OrchardCore.Search.Lucene.cspr
oj::TargetFramework=net8.0]

This is why I made the change to add the alias for the Lucene.Net.Store namespace. If there is a better way to solve that issue I am happy to use that, but this is the only way that I know.
