Migrate from deprecated `gopkg.in/yaml.v3` to `go.yaml.in/yaml/v3` maintained package

[bupd]

Summary

We currently use gopkg.in/yaml.v3, which is now deprecated. The YAML organization provides an officially maintained, drop-in compatible replacement at go.yaml.in/yaml/v3.
This new package is fully identical to go-yaml/yaml, actively maintained, and receives security updates.
