Change shape of booleans to be hexagonal

[manuq]

What Happened

This is a nice convention of Scratch and other block-coding languages. Boolean blocks and the slots that expect booleans are hexagonal or "pointy". This helps the user to understand where to add booleans.

Proposal: change the shape of value blocks to be pointy when the variant type is boolean. Same for the shape of slots that expect a boolean.

Here is how they look today:
