Bump markdown-it from 12.3.2 to 14.0.0

[dependabot]

Bumps markdown-it from 12.3.2 to 14.0.0.

Changelog

Sourced from markdown-it's changelog.

[14.0.0] - 2023-12-08

Changed

• Drop ancient browsers support (use .fromCodePoint and other features).
• Rewrite to ESM (including all plugins/deps). CJS fallback still available. No signatures changed, except markdown-it-emoji plugin.
• Dropped dist/ folder from repo, build on package publish.
• Set punicode.js as external dependency.

Fixed

• Html tokens inside img alt are now rendered as their original text, #896.
• Hardbreaks inside img alt are now rendered as newlines.

[13.0.2] - 2023-09-26

Security

• Fixed crash/infinite loop caused by linkify inline rule, #957.

Fixed

• Throw an error if 3rd party plugin doesn't increment line or pos counters (previously, markdown-it would likely go into infinite loop instead), #847.

[13.0.1] - 2022-05-03

Fixed

• Bumped linkify-it to 4.0.1. That should fix some hangs, caused by wrong data, returned from linkify-it.

[13.0.0] - 2022-04-22

Added

• Added a new token type text_special to store escaped characters, same as text but unaffected by replacement plugins (smartquotes, typographer, linkifier, etc.).
• Added a new rule text_join in core ruler. Text replacement plugins may choose to insert themselves before it.

Changed

• (p) is no longer replaced with § by typographer (conflicts with ℗), #763.
• text_collapse rule is renamed to fragments_join.

Fixed

• Smartquotes, typographic replacements and plain text links can now be escaped with backslash (e.g. \(c) or google\.com are no longer replaced).
• Fixed collision of emphasis and linkifier (so http://example.org/foo._bar_-_baz is now a single link, not emphasized). Emails and fuzzy links are not affected by this.
