Bjørn Erik Pedersen a3d9548469 Replace to gopkg.in/yaml with github.com/goccy/go-yaml (note)
This commit also adds validation to prevent the "Billion Laughs" attack (see https://github.com/goccy/go-yaml/issues/461). The limit of non-scalar aliases to the same node is set to 10,000. See benchmarks below.
