order_by does not work with Ecto 3.12

[sriedel]

Using ecto 3.12.5, attempting to sort the result of a query with the following query pipeline

iex(17)> TodoItem |> order_by(asc: :id) |> Repo.all

results in the error

** (FunctionClauseError) no function clause matching in anonymous fn/1 in Mongo.Ecto.NormalizedQuery.order/2

    The following arguments were given to anonymous fn/1 in Mongo.Ecto.NormalizedQuery.order/2:

        # 1
        %Ecto.Query.ByExpr{
          expr: [asc: {{:., [], [{:&, [], [0]}, :id]}, [], []}],
          file: "iex",
          line: 17,
          params: nil,
          subqueries: []
        }

    (mongodb_ecto 2.0.0-rc.2) lib/mongo_ecto/normalized_query.ex:772: anonymous fn/1 in Mongo.Ecto.NormalizedQuery.order/2

It seems the name of the Struct was changed from Query.QueryExpr to Query.ByExpr.
