Paginator: The dropdownItemTemplate property can't be configured to target the "jump to page" dropdown instead of the "rows per page" dropdown

[nicohenao]

Describe the bug

The Paginator component has two possible dropdowns to be displayed:

Rows per page dropdown (visible by default)

Jump to page dropdown (visible when the showJumpToPageDropdown property is set to true)

The problem

This component's API has an optional dropdownItemTemplate property to allow a custom template for the items of "the dropdown", but it is not clear which of the two possible dropdowns this property is targeted to. The documentation says: "Template instance to inject into the dropdown item inside in the paginator.", without specifying which of the two dropdowns will use the template for their items.

I found that it targets the "Rows per page" dropdown, but I was trying to display a custom template for the "Jump to page" dropdown so that I can customize the options for the page numbers in the dropdown (See the StackBlitz example).

Steps to reproduce the behavior

Setup a <p-paginator> element like the one in the StackBlitz example, set the showJumpToPageDropdown property to true, the showPageLinks property to false, and the dropdownItemTemplate to a TemplateRef defined in the HTML template as an <ng-template> and in the component's TS code as a @ViewChild property. (See the StackBlitz example).

You will see that the custom template does not get rendered anywhere (since the "rows per page" dropdown is not visible in this example, and should not be visible for a use case like this one), and there is not an option to inject a custom template to the "Jump to page" dropdown items.

Expected behavior

In my opinion, I should be able to choose which of the two dropdowns I want to customize with the template for the items, or better yet, a new property could be added to the Paginator's API to allow a custom template for the "jump to page" dropdown, similar to the dropdownItemTemplate property, without introducing breaking changes.
