Description

FLINK-33364 and FLINK-33577 added snakeyaml and pyyaml dependencies to support a standard YAML parser. However, these parsers support the YAML 1.1 specification rather than the YAML 1.2 specification, which is the version referenced by FLINK official website. Therefore, we need to update these dependencies that support YAML 1.2.

The updated dependencies are as follows:

1. For Java: change from snakeyaml to snakeyaml-engine
2. For Python: change from pyyaml to ruamel.yaml
