feat(parser): basic parsing element list with context bump

[ematipico]

Summary

This PR implements the basic parsing of a list of elements. The parsing of this list is inspired to the JSX parsing, where all trivia is parsed as a HtmlContent.

The lexer also adds some initial lexing of comments, although I haven't implemented any logic because I encountered some lexing issue that I prefer to solve after this PR lands.

Test Plan

I added new test cases
