Log Message:
py-ruamel-yaml: update to 0.18.5.

[0.18.5, 2023-11-03]:
- there is some indication that dependent packages have been pinned to use specific
  (tested) and just install the latest even in Python versions that have end-of-life

[0.18.4, 2023-11-01]:
- YAML() instance has a `doc_infos` attribute which is a cumulative list of DocInfo
  instances (one for `load()`, one per document for `load_all()`). DocInfo instances
  contain version information (requested, directive) and tag directive information
- fix issue that the YAML instance tags attribute was not reset between documents,
  resulting in mixing of tag directives of multiple documents. Now only provides tag
  directive information on latest document after loading. This means tags for dumping
  must be set **again** after a document is loaded with the same instance. (because
  of this tags will be removed in a favour of a different mechanism in the future)
- fix issue with multiple document intermixing YAML 1.2 and YAML 1.1, the \ 
VersionedResolver
  now resets
- fix issue with disappearing comment when next token was Tag (still can't have both
  a comment before a tag and after a tag, before node)

[0.18.3, 2023-10-29]:
- fix issue with spurious newline on first item after comment + nested block sequence
- additional links in the metadata on PyPI (Reported, with pointers how to fix, by
  [Sorin](https://sourceforge.net/u/ssbarnea/profile/)).
