golang-gopkg-yaml.v3-dev binary package in Ubuntu Jammy arm64

 The yaml package enables Go programs to very comfortably encode and decode
 YAML values. It was developed within Canonical as part of the juju project,
 and is based on a pure Go port of the well-known libyaml C library to parse
 and generate YAML data quickly and reliably.
 .
 The yaml package supports most of YAML 1.2, but preserves some behavior from
 1.1 for backwards compatibility.
 .
 Specifically, as of v3 of the yaml package:
 .
  * YAML 1.1 bools (yes/no, on/off) are supported as long as they are being
    decoded into a typed bool value. Otherwise they behave as a string.
    Booleans in YAML 1.2 are true/false only.
  * Octals encode and decode as 0777 per YAML 1.1, rather than 0o777 as
    specified in YAML 1.2, because most parsers still use the old format.
    Octals in the 0o777 format are supported though, so new files work.
  * Does not support base-60 floats. These are gone from YAML 1.2, and were
    actually never supported by this package as it's clearly a poor choice.
 .
 and offers backwards compatibility with YAML 1.1 in some cases. 1.2,
 including support for anchors, tags, map merging, etc. Multi-document
 unmarshalling is not yet implemented, and base-60 floats from YAML 1.1 are
 purposefully not supported since they're a poor design and are gone in YAML
 1.2.
