fix(cli): Fix package version check on Windows

[jsteinich]

For at least c#, the package version lookup is failing on Windows due to line endings. I went ahead and change the other languages as well.
I believe this is at least partially contributing to #1816.

I'd like to have a test for this, but I'm not sure the best spot. The unit tests aren't setup very well for checking this and I'd rather not make an entirely new integration test just for this.

Hm, I'd be open to both 🤷‍♂️ If it tests, it tests 😁

I'm working on this, as our CI is currently broken 🙃 fyi: I'll commit to your branch, hope that is fine with you @jsteinich :)
