Avoid popping the custom widgets snippet for local runtimes

[craigcitro-ant]

Describe the current behavior

Currently, when using a local runtime, any use of ipywidgets>=8 will pop up the code snippets pane with a suggestion to enable custom widgets:

There are two issues here:

1. enabling custom widgets won't help, as the root cause is that ipywidgets 8+ still isn't supported.
2. orthogonal to the widgets issue, popping up a custom google.colab-using snippet for a local runtime doesn't help -- we still can't easily install that package. 😉

This issue only tracks (2), but I'm happy to file an issue for (1) if someone has cycles.

3020 is the closest thing I could find to a tracking bug for (1), but it's closed; IMO would be worth a new bug tracking Pete's "... roll out proper support for ipywidgets>=8.0.0" bit in this comment.

Describe the expected behavior

Don't pop up a code snippet I can't use.

oh, man, i'm falling apart here. repro steps!

1. Start a local runtime
2. python3 -m pip install ipywidgets>=8.0.0

3. Run any tqdm-using snippet, eg:

   from tqdm.auto import tqdm
   
   for i in tqdm(range(3)):
     print(i)

Hi Craig! 👋🙂

Seems like it'd be good to have a tracking issue for (1) even if we don't immediately have the bandwidth.

For (2), I was able to repro. Found the relevant code in the UI. Not sure the best way to plumb the ipywidgets version through to the UI. Perhaps Katlyn knows, I'll ask.

This seems to be a work-around:

pip3 install 'ipywidgets<8'

+restart notebook.
