When trying to use config.sh

https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/User-Agent

We use dotnet's OSDescription to get a string that we then include in our UserAgent header as a ProductInfoHeaderValue.

The constructor of ProductInfoHeaderValue validates if a string is compliant with UserAgent formatting. There aren't many requirements, but one of them is matching brackets -> () Brackets represent a comment in a UserAgent.

Liquorix has an OS description that contains mismatched brackets, so the constructor of ProductInfoHeaderValue throws.

I'd probably go with dropping all () to prevent nested UserAgent comments
