improvement: suggest restarting the kernel for available but unloaded packages

[Light2Dark]

📝 Summary

Fixes #5554 . We could implement a better frontend experience but this surfaces the error at least.

edit: This doesn't work (doesn't detect the right one, + doesn't update)

Current way to find the module is naive. Another option is regex. I've come up with this as a possibility

# patterns = [
#     r"requires ['\"]?([\w_]+)['\"]?",  # "requires 'module'"
#     r"['\"]?([\w_]+)['\"]? module to be installed",  # "'module' module to be installed"
#     r"No module named ['\"]?([\w_]+)['\"]?",  # "No module named 'module'"
# ]
