py-soupsieve: updated to 1.9.4

1.9.4
- **FIX**: :checked rule was too strict with option elements. The specification \ 
for :checked does not require an
  option element to be under a select element.
- **FIX**: Fix level 4 :lang() wildcard match handling with singletons. Implicit \ 
wildcard matching should not
  match any singleton. Explicit wildcard matching (* in the language range: \ 
*-US) is allowed to match singletons.
