New myst-parser release

[chrisjsewell]

Hi all 👋,

I'm pleased to announce a new release of myst-parser (and myst-docutils),
that brings a number of exciting new features, improvements, and upgrades 🎉
https://myst-parser.readthedocs.io

• 📚 Rewritten documentation, with a clearer structure, many more examples, rich hover tips, and a new live preview page (powered by pyscript)
  • The code base API is also now fully documented by https://sphinx-autodoc2.readthedocs.io/, which even allows for MyST docstrings!
• ⬆️ Add Sphinx 6 support
• 📄 Extended docutils (single-page) support
• 🔗 Extended Markdown links, including intersphinx support, e.g. [text](inv:name#target)
• {} New attributes syntax, to extend common Markdown syntaxes, e.g. ![image](image.png){#id .class width=100px}

For a full list of changes, see: https://github.com/executablebooks/MyST-Parser/blob/master/CHANGELOG.md

Happy parsing! 🤖
