Make checkbox style closer to notion's

[FranciscoMoretti]

Description

Make checkbox style match notion's in the aspects described in this issue #356.

The checkbox visuals are a bit inconsistent with an official notion page.

• For checked: The size of the check mark is a bit bigger in react-notion-x
• For unchecked: The border is a bit thinner in react-notion-x

One of the builds fail, I'm not able to see the details in Vercel. When I click details it takes me to a 404 page.
