fix: (CXSPA-8035) NavigationUiComponent list-count not read out.

  * add condition to change lists role attribute to presentation if there is only one item to show to avoid narrating a list with one item

  * introduced a new translation

  * pass an ariaLabel attribute to cx-generic-link to get the title, list size and current position narrated by JAWS.

  * closes https://jira.tools.sap/browse/CXSPA-8035
