py-prompt_toolkit: updated to 3.0.48

3.0.48: 2024-09-25

Fixes:
- Typing improvements:
  * Add `@overload` to `contrib.regular_languages.compiler.Variables.get`.
  * Use `Sequence` instead of `list` for `words` argument in completers.
- Improve `ModalCursorShapeConfig`:
  * Display an "underscore" cursor in Vi's "replace single" \ 
mode, like
    "replace" mode.
  * Display an "beam" cursor in Emacs (insert) mode.
