Multi line comment based on !' -> '

[Lokplart]

How can I make my multi line comment go from " !’ " to the last unmatched " ’ "

So:
!’ a = ‘b’
m = ‘s’
’
The comment would need to go until the last quote on line 3

are the smart quotes intentional?
if not, maybe something like:

%YAML 1.2

      scope: punctuation.definition.comment.begin.suffix
      push:
        - meta_scope: comment.block.suffix
        - match: '''[^'']*'''
        #- match: '''(?![^'']*'')'
        - match: ''''
          scope: punctuation.definition.comment.end.suffix
          pop: true
