fix(integrations): reduce excessive bottom space in honeycomb grid (#7511)

The HoneycombGrid ul element had an extra 46px added to its explicit
height (calc(height + 46px)). Since the height is already calculated
precisely in Honeycomb.js based on hexagon row counts, this 46px
surplus was creating empty vertical space below the last row of
integrations on the /integrations page.

Reduced from +46px to +3px (matching the margin value applied to each
li element) to eliminate the visual gap while preserving the small
buffer needed for the bottom row's top margin.
