Fix typos and omissions in HTML types

[andersk]

I went through the entire list of HTML elements, attributes, and ARIA attributes in the specification, making all needed additions and fixes, except that <math> is still missing because it will need separate treatment like <svg>.

Here’s a test file I wrote to exercise all of these elements and attributes: https://gist.github.com/andersk/8dd6578d23533ef6ee9a51fdec2b5b8c

Hmm, I wonder if we can merge this with https://github.com/potahtml/namespace-jsx-project.

@andersk Thanks! That project looks very interesting, and would love to see us generate our types from an exhaustive list.
