refactor: create a generic taxonomy widget (#1268)

* refactor: introduce a generic taxonomy widget and refactor existing category and tag cloud widgets to use it.

* feat: Implement optional title linking for taxonomy widgets and enable parameter customization for taxonomy partials.

* refactor: remove fallback to taxonomy page title for widget display

Because this field always exists. I think it's better to let user customize via widget params

* Update layouts/_partials/widget/taxonomy.html

* refactor: check for .Params.taxonomy existence before accessing

layouts/_partials/widget/categories.html
