Upgrade default pulldown-cmark to 0.13.0

Summary:
Upgrade the default pulldown-cmark alias from 0.9.1 to 0.13.0 and fix all
downstream consumers for the breaking API changes:

- Event::End now carries TagEnd instead of Tag
- Tag::Heading, Tag::Link, Tag::Image are now struct variants
- Tag::BlockQuote now takes Option<BlockQuoteKind>
- New Event variants: InlineMath, DisplayMath, InlineHtml

Fixed consumers:
- phabricator/service/handlers/rust/rust_parser.rs
- pyrefly/crates/pyrefly_config/src/error_kind.rs
- tools/gsd/src/lexical/markdown_converter.rs
- scripts/sxiao/portal/src/markdown/mod.rs

hphp/hack/src/hh_manual already uses Event::End(_) wildcard and needs no change.
