feature: Checkbox-like highlights for bullet points

[Asterikss]

Is your feature request related to a problem? Please describe.

I take notes almost exclusively in bullet points. It would be awesome if they received the same visual treatment as TODO items (checkboxes). Color distinction really goes a long way when they are nested, and would provide a nice touch visually, breaking the repetitiveness when dealing with long lists.

Describe the solution you'd like

With the current setup for checkboxes in mind:

checkbox = {
  -- ...
  custom = {
    uncertain = {
      rendered = 'ʕ•ᴥ•ʔ?',
      highlight = 'MyHighlight',
      scope_highlight = 'MyHighlight'
    },
  },
}

I would like to be able to customize bullets in a similar manner:

bullet = {
  icons = { '✿', '♞', '✺', '❅' },
  highlight = {'MyHighlight' , 'AnotherHighlight', 'X', 'Y'},
  scope_highlight = {'MyHighlight2' , 'A', 'B', 'C'},
}

So that each level could receive its own color for both the bullet point icon and its contents, just like with checkboxes.

Setting one highlight would cascade down, resulting in the same-looking highlight, as with the current one-highlight bullet setup (similarly to how the icons field works).

Describe alternatives you've considered

I imagine highlights would be indexed similarly to how icons are indexed, but maybe there is a better way.

highlight & scope_highlight support string, string[], string[][], or function as their type, so up to you which you provide. The example you gave should work.
