Update dependency yamldotnet to v16 (#1659)

renovate[bot] · JamieMagee · web-flow · commit e537f1d1e549 · 2026-02-19T17:01:17.000-05:00
* Update dependency yamldotnet to v16

* Fix YarnBerryTypeConverter for YamlDotNet 16 interface changes

YamlDotNet 16 changed IYamlTypeConverter: ReadYaml now takes an
ObjectDeserializer parameter, WriteYaml now takes an ObjectSerializer
and the value is nullable. Updated both method signatures to match.

Removed #nullable disable since the interface requires object?.
