Fix rendering of history items in members filter bar

What does this MR do?

Follow-up to #228675 (closed) and !48272 (merged)

app/assets/javascripts/vue_shared/components/filtered_search_bar/filtered_search_bar_root.vue history dropdown does not support GlFilteredSearchToken with option titles. For example:

{
  type: 'with_inherited_permissions',
  icon: 'group',
  title: s__('Members|Membership'),
  token: GlFilteredSearchToken,
  unique: true,
  operators: [{ value: '=', description: 'is' }],
  options: [
    { value: 'exclude', title: s__('Members|Direct') },
    { value: 'only', title: s__('Members|Inherited') },
  ],
},

This MR adds support for the title attribute on options
