TL;DR

Remove redundant YAML packages: github.com/ghodss/yaml and gopkg.in/yaml.v2

Type

Complete description

Currently four YAML packages are used:

1. github.com/ghodss/yaml
2. gopkg.in/yaml.v2
3. gopkg.in/yaml.v3
4. sigs.k8s.io/yaml

We can keep only two of them:

1. gopkg.in/yaml.v3
2. sigs.k8s.io/yaml

The package github.com/ghodss/yaml is no longer actively maintained. See discussion in ghodss/yaml#80 and ghodss/yaml#75. sigs.k8s.io/yaml is a permanent fork of ghodss/yaml and is actively maintained by Kubernetes SIG, also widely used in K8s projects.

We are only using gopkg.in/yaml.v2 in cmd/config/subcommand/project/project_config.go. Switching to gopkg.in/yaml.v3 doesn't introduce breaking change here.
