[2.0.77] Lithium brine pumpjack UI doesn't display lithium per sec

[MondSemmel]

Expected behavior: Oil pumpjacks display how much oil they produce per second: https://i.imgur.com/uVNF4zr.png

Bug: Lithium brine pumpjacks don't display in their UI how much lithium they produce per second: https://i.imgur.com/jOoqmbA.png <-> I initially suspected this behavior might be caused by the pumpjack producing <1 item per sec, but it happens even at >1 item per sec.

Reproducibility: This always happens, consistently.

Thanks for the report however this is working correctly. "Amount per second" is only shown for infinite type resources and lithium brine is not infinite.
