chore: update some DE regions

[dersvenhesse]

I checked some German provider and their links and updated those.

Thank you @dersvenhesse for keeping systems.csv up to date with the reality 🙏

I've done some research and can't find any article indicating that these Donkey Republic and Lime systems have been permanently shut down.

Therefore, I suggest keeping these feeds in systems.csv, unless you have evidence that these systems have been permanently shut down, other than the fact that their GBFS feeds are empty.

This is to avoid removing feeds that might become active again in the future (temporary seasonal shutdown, temporary bug in the feed, etc.).

Thanks again for your help!

About those removed Donkeys, I found a source for Berlin

Der Anbieter Donkey Republic bietet keine Fahrräder zum Verleih mehr in Berlin an.

and suppose those other cities are removed as well since there are no vehicles listed in the official Donkey app.

It's a great idea to check the operator's app when no news article is available. Thank you @dersvenhesse!

Here are screenshots from the operator's apps showing that the systems are shutdown.

Donkey Republic:

Freiburg	Munich

Lime:

Reutlingen	Solingen

@dersvenhesse Could you please add back Lime Oberhausen? The operator's app shows vehicles available. Thank you!

LGTM! Thank you @dersvenhesse 🙏
