update rustc_ast crate descriptions in documentation

I noticed this the other day and figured I'd suggest a refresh. It seems like a relic from the days of `libsyntax` that got missed as things were split out into separate crates, since the current documentation text references elements that were moved into their own respective crates (e.g. `rustc_parse`)

The `rustc_ast` crate contains those things concerned purely with syntax
– that is, the AST ("abstract syntax tree"), parser, pretty-printer,
lexer, macro expander, and utilities for traversing ASTs.
– that is, the AST ("abstract syntax tree"), along with some definitions for tokens and token streams, data structures/traits for mutating ASTs, and shared definitions for other AST-related parts of the compiler (like the lexer and macro-expansion).
For more information about how these things work in rustc, see the
rustc dev guide:
