During preparing for the latest driver release, we noticed that if the release branch has lower (or equal) version of mongocrypt library than the master and if the master branch had already been released before (without cleaning temp files), the mongocrypt library in the new release won't replace the previous one. So the actually existed mongocrypt library will still be from the master.

To fix it, this value(and similar) should be replaced on Always: https://github.com/mongodb/libmongocrypt/blob/master/bindings/cs/MongoDB.Libmongocrypt/MongoDB.Libmongocrypt.csproj#L92
