Elixir 1.19: Fix typing violation on struct updates in Pleroma.Upload

warning: a struct for Pleroma.Upload is expected on struct update:

        %Pleroma.Upload{
          upload
          | path:
              case upload.path do
                x when x === false or x === nil ->
                  <<to_string(upload.id)::binary, "/", to_string(upload.name)::binary>>

                x ->
                  x
              end
        }

    but got type:

        dynamic()

    where "upload" was given the type:

        # type: dynamic()
        # from: lib/pleroma/upload.ex:95:24
        {:ok, upload} <- prepare_upload(upload, opts)

    when defining the variable "upload", you must also pattern match on "%Pleroma.Upload{}".

    hint: given pattern matching is enough to catch typing errors, you may optionally convert the struct update into a map update. For example, instead of:

        user = some_function()
        %User{user | name: "John Doe"}

    it is enough to write:

        %User{} = user = some_function()
        %{user | name: "John Doe"}
