feat(Select): maintain size of select fields after value selection (#1899)

## 📝 Changes

A Select with size="md" or size="lg" shrinks by one size step once a
value is selected: md renders like sm, and lg renders like md, while sm
is unaffected.
Hardcoding variant="body2" on the selected value overrides the inherited
size, causing md and lg to render with the smaller body2 style.
Remove the hardcoded variant="body2" so the selected value inherits the
trigger's size

+Select now keeps its size after you choose a value, so medium and large fields stay the same height instead of shrinking a step
