Newline is not possible on the Windows environment

[webwarrior06]

What happened:
I am trying to use templates on windows. But, It seems that the new line keyword is not working.

What you expected to happen:
It should give a line break with the proper command.

How to reproduce it (as minimally and precisely as possible):
Just use the example shown on the Readme.MD
kubectl stern -n company myservice -t --since 10m --context aks-dev-westeurope-cluster --color always --template '{{ .Message}} {{"\n"}} '

Anything else we need to know?:
No

Environment: Windows 10 64 Bit

• stern version (use stern --version): 1.20.1
• OS (e.g: cat /etc/os-release):
• Install tools (e.g: Homebrew)
• Others:

It work on both Linux and macOS. Unfortunately, I do not have a Windows environment, so it is difficult to reproduce the problem.
