Drawer: Footer Div/Slot added by default

[ShrinidhiRajeevKulal]

Describe the bug

In PrimeVue version 4, the Drawer component automatically includes a footer div or footer slot by default. This behavior occurs even when the footer slot is not explicitly mentioned or needed. We would prefer the footer to only be added when explicitly defined.
