config: use correct YAML marshal func (#9712)

The `compose-spec/compose-go` lib is written with `gopkg.in/yaml.v2`
as a target.

When marshalling via CLI (`compose convert` / `compose config`), we
were using a _different_ YAML lib, which was a fork of `go-yaml`,
which is what `gopkg.in/yaml.v2` is based off of.
