## What kind of change does this PR introduce?
Bug fix.
## What is the current behavior?
Product menu section dividers use the stronger `border-overlay` colour,
while the product heading divider uses `border-default`.
## What is the new behavior?
Product menu section dividers use the same `border-default` token as the
product heading divider in light and dark mode.
