Issue:
The drop-down value is not being selected while navigating the item list through keyboard up/down arrow keys in the latest release version (17) – PrimeNG v17 Accessibility. This functionality was working in the previous release version (15) – PrimeNG v15 Accessibility.

Environment:

Angular version: 17.3.6
PrimeNG version: 17.16.0
Node version: 18.16.1
Language: TypeScript
Steps to Reproduce:

Navigate to p-dropdown using the keyboard tab key.
Press the space key or enter key to open the drop-down.
Press the up/down arrow keys.
Observe the drop-down value. It is not being selected with arrow key navigation. The user has to press the enter key to select the highlighted value.

Tried Solutions:

Updated PrimeNG version

Expected Behavior:
The drop-down value should be selected while navigating with the up/down arrow keys, as in the previous version (15), along with the enter key and spacebar key.
