Replace unmaintained yaml library with a new one

[baruchiro]

We are using an old yaml parsing package, which, for example, doesn't support omitempty.

https://github.com/Checkmarx/2ms/blob/master/reporting/yaml.go#L7-L14

I want to replace it with one of the newer packages:

• https://github.com/kubernetes-sigs/yaml
• https://github.com/goccy/go-yaml

Please discuss here which package you suggest, and after my approval, replace the current go-yaml/yaml with the newly selected package.

Also consider upgrading to v3 of the existing library. (It's newer by 2 years... although not active since)
