Subject: [PATCH] fix(notification): change box-shadow to border (#4299)

This change also makes inline notification's text color non-themeable
for now, given the background color is non-themeable and making it
themeable requires themeable component-specific token (or new global
theme tokens).

This stop-gap approach may be enough for short team because IIRC
low-contrast notifications is there for a backword-compatibility
reason.
