Opening hours with '\n' in time field

[SiKreuz]

Steps to Reproduce

1. Open Opening Hours Activity
2. Go to the detailed view of a sub section
3. The time values are sometimes more than just a simple one line string, but with multiple lines and \n. Probably received like that from the API and not properly formatted.

Environment

Phone: OnePlus 5T
OS version: OxygenOS 10.0.1
TUM Campus App version: v3.9-dev
Language: German & English

Can confirm it's the server who's at fault here. The newlines within the json vary among literal "\\n", "\/n" and "\n". Both 1 and 2 are essentially wrong following ECMA 404. Number 1 is where this issue appears, number 2 is "fixed" by the weird string-replace stuff happening here.

Gson (correctly) interprets the "\\n" in the json as literal "\n", "\/n" as "/n", and "\n" as an actual newline character. While number 1 probably occurs because of a single escaping backslash too many (in the json source), I don't really see why number 2 would happen, even though it seems to be the most frequent by far.
Other json elements are also affected (like "infos").

Opening hours are simply stored in the backend and retrieved by the app, we can easily replace any inconsistencies there I suppose. @SiKreuz you can open this in https://github.com/TUM-Dev/Backend if you want.
