Let's see if traitlets 5.11.1 reduces the number of errors.

@blink1073 would you have time to provide advice on how to fix the issues related to the new traitlets typing?

• for all the handlers, parent is an HasTraits
  • needs to be refined to e.g. LabApp
    • this can be done in a `if TYPE_CHECKING: assert isinstance(parent, LabApp)
• app_name and open_browser
  • this pattern has always been kinda annoying, as it breaks configurability
  • could be either
    • re-defined as e.g Unicode("JupyterLab Server Application").tag(config=True)
    • or with a @default value further down

Thanks @bollwyvl and @blink1073 for finishing this one.
