p-menu w/ popup: enter key on number pad doesn't select menu item (accessibility issue)

[Da13Harris]

Describe the bug

There are two enter keys on most standard keyboards, one next to the alphanumeric keys and one next to the number pad.

Using a standard <p-menu [popup]="true">, you can trigger an item using the primary enter key, but you can't when using the enter key on the keyboard's number pad.

Steps to reproduce the behavior

Using the menu in the supplied StackBlitz reproduction, you can select an item using the primary enter key, but you can't when using the enter key on the keyboard's number pad.

Expected behavior

The enter key on the keyboard number pad should trigger menu options, just like the standard enter key does.
