Accessibility: Calendar opens automatically when receiving focus

[danalt06]

Describe the bug

The PrimeReact Calendar/DatePicker popup opens automatically when the Calendar trigger receives keyboard focus.
Simply focusing an interactive control should not activate or expand it.

Reproducible on the primereact documentation page: https://v9.primereact.org/calendar/
