NavList.Group should pass all props through to the ActionList.Group

[mattcosta7]

Describe the bug

react/src/NavList/NavList.tsx

Line 244 in 53713b2

const Group = ({title, children, sx: sxProp = {}}: NavListGroupProps) => {

(as a nit here - using sx = {} in the function definition means every render by default supplies a new sx object. sx = defaultSx, where previously const defaultSx = {} would avoid that

NavList.Group only accepts a handful of props from ActionList.Group, and should probably accept almost/all and pass them through, specifically for things like aria attributes and data props, for test ids, etc
