Make reserveScrollBarGap optional when lockScroll is enabled

Describe the solution you'd like

Add a reserveScrollBarGap boolean to VueFinalModal props, have it dynamically set the boolean when enabling bodyScrollLock.

Additional context

I have overflow-y-scroll set on my html element which shows the scrollbar permanently. Therefore I don't need the additional padding.

Faced with the same problem, I use the scrollbar-gutter: stable property. The reserveScrollBarGap property should be optional.
