Repository: helm-unittest/helm-unittest

Issue:
Replace gopkg.in/yaml.v3 dependency as it is outdated and unmaintained
**Describe the bug**
There has been no activity on the `gopkg.in/yaml.v3` repo from its maintainers for over two years. There are over 100 open PRs and nearly 300 unresolved issues, including one from a contributor offering to take over maintainership. Most of the mentioned issues indirectly affect helm-unittest.

**To Reproduce**
Go to https://github.com/go-yaml/yaml and see there is no activity from the maintainer.

**Expected behavior**
helm-unittest uses up-to-date and maintained dependencies.



Discussion:
@ivankatliarchuk: There is no drop-in replacement. 

Example helm uses `sigs.k8s.io/yaml` which is a wrapper/fork `https://github.com/kubernetes-sigs/yaml/tree/master/goyaml.v3`@ivankatliarchuk: 5+ years old unmainted dependent library "https://github.com/dprotaso/go-yit" and 4+ unmainted library "github.com/vmware-labs/yaml-jsonpath/pkg/yamlpath"


Problem with `gopkg.in/yaml.v3` it uses no interfaces, so the only way is to rewrite things from the ground@quintush: Hello @V02460 

Thanks for the feedback.
As mentioned by @ivankatliarchuk there are more libraries outdated.

We have started isolating the libraries, and will make contact to other maintainers to see if they are also willing to update their libraries.

Currently some of the used libraries have functionality where I haven't found a replacement for.

Greetings,
@quintush @afalhambra-hivemq: Is there any update about this?@ivankatliarchuk: Helm itself still rely on same dependency https://github.com/helm/helm/blob/4d580c6b95760be89a5131fa4ca7cd9e13cec792/go.mod#L37

I manage to get quite close with https://github.com/goccy/go-yaml, but at the moment not convinced is not going to break things@ivankatliarchuk: Helm recently migrated to https://github.com/yaml/go-yaml/tree/main, is here https://github.com/helm/helm/blob/c5901abba66a634e5854bdc89fa10b0a392ae937/go.mod#L34 and kube yaml is migration to same library https://github.com/kubernetes-sigs/yaml/issues/18
