[3.12] gh-111726: Remove some doctests from sqlite3 docs (GH-117623) (#117625)

Browse source 
* remove load extension doctest since we cannot skip it conditionally
* remove sys.unraisablehook example; using unraisable hooks is not "an
  improved debug experience"

(cherry picked from commit e338e1a4ec)

Register an :func:`unraisable hook handler <sys.unraisablehook>` for an
improved debug experience:

Errors in user-defined function callbacks are logged as unraisable exceptions.

introspection of the failed callback.
