add sphinx-copybutton configurations to exclude prompts
- [ ] closes #59369


It is easy to combine the extensions `sphinx_copybutton` and `sphinx_toggleprompt`, but `sphinx_toggleprompt` doesn't support the `ipython` layout. See a minimal example I made with the code from the [beginners section](https://pandas.pydata.org/docs/user_guide/index.html#how-to-read-these-guides).

If the regular expression from `sphinx_copybutton` isn't activated, it is not possible to copy the code from the first block to the clipboard without the output lines. This is not user friendly.

Combining these two extensions for a supported layout will result in two clicks for the user to copy the code. And in my humble opinion this is one click to much.
 @mroeschke Could you please give me some feedback to the current version. Otherwise I am about to close this PR, because it is out of my personal scope.
