Bootstrap 5.3.3 upgrade breaks Blazor template styling

[danroth27]

The Bootstrap 5.3.3 upgrade seems to break some of the styling in the Blazor template. The horizontal padding on the nav links is missing:

Before (.NET 8):

After (.NET 9):

This appears to be partially due to some undefined CSS variables that Bootstrap started using in 5.2:

.NET SDK version: 9.0.100-rc.2.24474.11

I don't see how this fixes the undefined variables, anyone have insight on how to get these to load
