Add extra checkbox giving the option to globally hide the dialog "Restart Kernel? ... All variables will be lost"

Problem

Ticking the checkbox in "Restart Kernel? ... All variables will be lost" works, in my experience, only for the current env; the next time you recreate a Python environment the dialog will show up again.

I disabled it globally by adding

{                                                                                              
    "skipKernelRestartDialog": true
}

to ~/.jupyter/lab/user-settings/@jupyterlab/apputils-extension/sessionDialogs.jupyterlab-settings.

Still, I find the dialog misleading.

Proposed Solution

• Modify the text in the dialog from "Do not ask me again." to "Do not ask me again, in the current Python environment." (or equivalent text).
• Ideally: add a new checkbox with the text "Do not ask me again, in any Python environment (current user)." (or equivalent text).
