Is your feature request related to a problem? Please describe.
Radioitem and checklist options typically have short labels so sometimes it would be helpful to add a descriptive tooltip to them. For a user-defined label, this is possible via html.Label(title="…"). For labels created through RadioItem or Checklist, this does not seem possible.

Describe the solution you'd like
In addition to disabled, label, value, allow setting the title on an option.

Describe alternatives you've considered
I've seen a workaround using dbc but apart from requiring the bootstrap components, that solution is somewhat complicated and does not match the workflow of the html.Label component.
