Auto-drop incorrect wrapping quotes in values

[tidoust]

Pending resolution of speced/bikeshed#3011 or updates made to underlying specs, this adds a temporary mechanism to drop offending wrapping single quotes in the definitions of properties and values during data curation, so that we may publish a new version of @webref/css while the problem gets fixed.

noting that this stretches the semantics implied by the file name :)

(relatedly, to confirm my understanding - if this wasn't a temporary thing with the associated pain of sync'd releases, it would more logically fit as a reffy post-processing item, right?)

Surely, file names are meant to be opaque ;)

Boundaries are probably not as crisp as I'd like them to be, but the nuance I keep in mind between post-processing in Reffy and data curation in Webref is that the former may complete the data but it does not "patch" or curate it. As such, I would probably argue that this patching logic needs to stay in Webref (renaming the script to be more generically about curating css properties and values). Of course, dfns patching is already an exception to the rule, but that's due to the fact that we don't actually curate dfns extracts in Webref for now, whereas we do curate CSS/IDL extracts.
