Resolves #6373
Forward-port of PR #5793
See that PR for some discussion.
Because SnakeYAML 2.0 contains backward-incompatible changes to its API, this PR includes two integration tests to make sure users can use the older version of SnakeYAML if they need to, one for reactive (basically the same as the SE test from the 3.x PR) and a new one for Níma.
The PR also repairs a bug introduced in the OpenAPI code when it was ported from SE/reactive to Nima.
