Log Message:
py-ruamel-yaml: update to 0.18.2.

[0.18.2, 2023-10-24]:
- calling the deprecated functions now raises an `AttributeError` with the, somewhat
  more informative, orginal warning message. Instead of calling `sys.exit(1)`

[0.18.1, 2023-10-24]:
- calling the deprecated functions now always displays the warning message. (reported
  by [Trend Lloyd](https://sourceforge.net/u/lathiat2/profile/))

[0.18.0, 2023-10-23]:
- the **functions** `scan`, `parse`, `compose`, `load`, `emit`, `serialize`, `dump`
  and their variants (`_all`, `safe_`, `round_trip_`, etc) have been deprecated (the
  same named **methods** on `YAML()` instances are, of course, still there.
- |-
  `YAML(typ='unsafe')` now issues a `PendingDeprecationWarning`. This will \ 
become deprecated in the 0.18 series
  (probably before the end of 2023).
  You can use `YAML(typ='full')` to dump unregistered Python classes/functions.
  For loading you'll have to register your classes/functions
  if you want the old, unsafe, functionality. You can still load any tag, like \ 
`!!python/name:posix.system', **safely**
  with the (default) round-trip parser.
- fix for `bytes-like object is required not 'str' while dumping binary streams`.
  This was reported, analysed and a fix provided by [Vit \ 
Zikmund](https://sourceforge.net/u/tlwhitec/profile/)
