[web] Replace cloud-filled icon in ChatThreadAncestors with CommIcon
Summary:
Searched through codebase for usages of cloud-filled and found one instance in the ChatThreadAncestors component.
Swapped out the SWMansionIcon component for the CommIcon component.
NOTE: Going to create individual diffs for all usages of each icon for CommIcons to make the before/after clear. There are only 6 custom CommIcons so this shouldn't produce too much spam.
Test Plan:
WARNING: The actual icon changed. I'm using the same cloud icon we decided with Alicja to go with on native. I strongly think we should go with the same filled cloud icon on web because A. consistency B. it looks a lot better than an open path.
