Upgrade to SnakeYAML 2.0

This commit raises the SnakeYAML baseline version to 2.0.
While most Spring applications are not affected by CVE-2022-1471,
upgrading this version should prevent automated tools from raising this
as a security issue. Such tools usually do not understand that YAML
parsing in Spring is about reading configuration, not parsing untrusted
content.

Closes gh-30048
