Fix yaml-ts-mode comment-start-skip to improve commenting/uncommenting

* lisp/textmodes/yaml-ts-mode.el (yaml-ts-mode): Fix 'comment-start-skip'
value to resolve an issue when commenting/uncommenting using the
'comment-or-uncomment-region' function.  The previous 'comment-start-skip'
value left some "-" uncommented after commenting and uncommenting
multiple YAML indented blocks (bug#78892).
