Refine heading options

Is your feature request related to a problem? Please describe.
For UX and aesthetic purposes, I suggest adjusting the heading options and the spacing between them.

Describe the solution you'd like
Rather than six heading options, I would suggest 3 like Notion (big, medium, small). I also suggest adjusting the spacing between the heading blocks, as they are currently not standardized:

I like this, simplifies things quite a bit 👍

@eccogrinder just an edge case I'm thinking through here, but in the situation where someone pastes in existing markdown that includes h4-h6's, we would just convert those to h3's, yeah?

@juliopavila do you think it would be complicated to do this and also maintain the original tag? IE: We apply the h3 style, but we render the title in an h5 for example.

Yeah, I think that would make the most sense.
