More info sheet: give each action button its own tap target

Directions and Report issue both fired on any tap inside their row: with the
default button style a List row has a single row-wide tap target, so tapping
one button triggered the other's action too (tapping Report issue opened Apple
Maps, and tapping Directions showed the report alert).

`.buttonStyle(.borderless)` gives each button its own hit area over its
half-row frame. Verified with real simulated taps on both buttons.
