feat(parser/html): correctly parse void elements

[dyc3]

Summary

Void elements are elements whose content model is "nothing", meaning that they should not have an end tag, and therefore, have no children.
In browsers, this requirement is imposed very forgivingly. Given that Biome doesn't aim to write browser-grade parsers, we can afford to be a little more strict.

The parser now checks the tag name to know if it should be self closing. If it encounters a closing tag for a void element, it will emit a diagnostic.

Test Plan

Added snapshot tests.

See the HTML spec: https://html.spec.whatwg.org/#void-elements

Given that Biome doesn't aim to write browser-grade parsers, we can afford to be a little more strict.

I would like to bring this topic to the table and discuss it, eventually. I would be open to make the parser a bit more forgiving, and still emitting warnings/errors, using our error resilience parser.

FYI, Astro's parser is way closer to a browser parser, because they can enable streaming during rendering.

I believe that also Svelte recently changed their approach.
