replaced serde_yml with serde_norway

[DenuxPlays]

@domenicquirl has mentioned that serde_yml is actually a very bad replacement for serde_yaml.

I've chosen serde_norway as the replacement.
A fork of the original serde_yaml and way better.

For more information see the discussion here: #1168 (comment)

I am very sorry for introducing this dependency.
This pr should fix my error.

I've serde_norway is not wanted we could also go with https://github.com/acatton/serde-yaml-ng
