[2.0.28] German spelling mistake in the research tree

[VarmintLP]

Hey,

I think it's fairly easy to keep it short this time.

"Kunststoffstangen <Number>" is missing the first N as seen on the picture.
It's the same for number 4 and I assume for the translation you certainly reuse the first word and add the number at the end since it's an infinity research point. No need to stress the game still runs fine. I cannot confirm if it was present before or not but I noticed it now since I just got to make progress on that research.
