Fix: Info icon in PvoTNavBar renders oval instead of circular

[Roniscend]

This PR fixes the incorrect oval rendering of the info icon in the PvoTNavBar, ensuring it appears circular and consistent with the other navigation icons.
Fixes: #20

Adjusts PvotNavBar default sizing to prevent the info tab/icon from appearing oval by reducing overall horizontal padding and inter-item spacing so collapsed items have enough width to remain circular.

Changes:

• Reduced PvotNavBarSizes.horizontalPadding default.
• Reduced PvotNavBarSizes.contentPaddingHorizontal default.
• Reduced PvotNavBarSizes.itemSpacing default.

@Roniscend have you tested this in multiple resolutions?

Because on my phones the info icon is circular, and on changing resolution it becomes oval.

This is not an issue with values, but the rendering of the navigation bar, which is a major blocker for releasing the library :/

[Roniscend]

I have added horizontal scrolling to the navigation row , which allows button to maintain their shape and size. Also I have tested this in multiple screens as well and it is working fine.
