Autocomplete multiple accessibility

[AtiposEiji]

Describe the bug

Using Axe DevTools, the autoComplete component with the multiple property has two accessibility issues:

1. ARIA input fields must have an accessible name
   Ensure every ARIA input field has an accessible name
   <ul role="listbox" ng-reflect-ng-class="[object Object]" tabindex="-1" aria-orientation="horizontal" class="p-autocomplete-multiple- container p-component p-inputtext ng-star-inserted">

   To solve this problem, you need to fix at least (1) of the following:

   • aria-label attribute does not exist or is empty
   • aria-labelledby attribute does not exist, references elements that do not exist or references elements that are empty
   • Element has no title attribute

2. Interactive controls must not be nested
   Ensure interactive controls are not nested as they are not always announced by screen readers or can cause focus problems for assistive
   technologies.

   <li role="option" class="p-autocomplete-input-token"><input pautofocus="" role="combobox" aria-autocomplete="list" class="p-element" ng-reflect-ng-class="[object Object]" autocomplete="off" tabindex="0" type="text" id="tags" placeholder="Seleziona" aria- expanded="false"></li>

   To solve this problem, you need to fix the following:
   Element has focusable descendants
