Subject: [PATCH] Disable yaml duplicate keys warning by default
Disable Yaml's warnOnDuplicateKeys by deafault to
follow the original behavior
It's just a warning output introduced since snakeyaml 2.4,
See https://github.com/snakeyaml/snakeyaml/commit/b16f9485f33136fb30f8472f3ccf0209707c023e
The comment of LoaderOptions#setWarnOnDuplicateKeys is
actually misleading, since this warnOnDuplicateKeys option
is enabled by default when creates new Yaml instance
