[3.11] gh-95132: Correctly relay *args and **kwds from sqlite3.connect to factory (GH-95146) (#95158)

This PR partially reverts gh-24421 (PR) and fixes the remaining concerns
given in gh-93044 (issue):

- keyword arguments are passed as positional arguments to factory()
- if an argument is not passed to sqlite3.connect(), its default value
  is passed to factory()
