Bump pulldown-cmark-to-cmark from 22.0.1 to 23.0.0

[dependabot]

Bumps pulldown-cmark-to-cmark from 22.0.1 to 23.0.0.

Release notes

Sourced from pulldown-cmark-to-cmark's releases.

v23.0.0

Beware that this is basically an SI rewrite, which I reviewed from an API perspective. It should be way more correct than the previous version, at least tests would say so.

Reason: I wanted to prevent piece-meal SI-PRs to fix individual aspects of the prior version, which was pretty sub-par in the correctness department.

New Features (BREAKING)

• require parser options and validate round-trip configurations

  Checked public API, rest is mostly rubber-stamped

  Make the originating parser flags mandatory in State::new and every cmark helper so escaping and source validation agree with the parser. Remove State::default(), default to symbolic superscripts/subscripts, and add optional, recommended Options::validate. Support all subsets of twelve modern extensions with standard markers: 491,520 finite configurations are accepted and 5,799,936 are explicitly rejected.

  Preserve mandatory list and definition boundaries, nested delimiter runs, math/table interactions, and raw blocks ending at EOF or by dedentation. Validate delimiter choices before emitting them and report unrepresentable blocks instead of silently changing events. Preserve list structure that relied on invisible definitions by reserving a collision-free label; these exceptional lists buffer the remaining input until finish.

  Keep accumulated reference occurrences and labels out of block-rendering snapshots. Criterion benchmarks cover shared, distinct, edited, and nested references at 1,000–8,000 paragraphs and show proportional scaling.

  Add permanent differential tests with exact merged-event comparisons across both rendering paths, 860 retained regressions, 91,446 generated inputs, symbolic extension combinations, numeric preferences, and every accepted configuration. Run the exhaustive release suite in CI. Document migration, validation, coverage counts, and commands that print the results.

• round-trip the full CommonMark 0.31.2 spec

  Rubber-stamp mostly, and nearly 1000 SLOC less seem to speak a clear language. I at least validated the public API which seemed sensible. The new API is definitely nicer, the tests are cleaned up.

  All 652 CommonMark 0.31.2 examples now round-trip with their parsed structure intact under default formatting. This includes paragraph boundaries, tight and loose lists, link types, and indented versus fenced

Author says this is a rewrite. I would let it bake some more before merging it.
