Pymdown-extensions

- **NEW**: Upgrade Twemoji to use 12.1.3.
- **NEW**: Downgrade and lock EmojiOne version 2.2.7. 2.2.7 is the last truly free version of EmojiOne. This is the safest version that users should use. EmojiOne will not be updated anymore as they are now JoyPixels and have a license that is not that permissible. We've reverted support for any version greater than 2.2.7 to ensure we don't accidentally cause a user to improperly use JoyPixels' assets.
- **NEW**: Drop specialized `to_awesome` generator for EmojiOne.
- **FIX**: MagicLink: match the auto-link pattern in the current Markdown package.
- **FIX**: Fix fenced math escape issue when using MathJax script output format.

- **NEW**: Upgrade Twemoji to 12.1.2 using the latest JoyPixels' (formally EmojiOne) short name index in JoyPixels/emoji-toolkit 5.0.4.
- **NEW**: Upgrade EmojiOne to 4.5.0 to the last release in the 4+ series. EmojiOne was rebranded as JoyPixels, but while the index is licensed under MIT, the image assets are no longer as permissible as they once were. The Emoji extension will only reference the last release under the older more permissible license (4.5.0). The option to use the CDN with EmojiOne 2.7 is still available as well which used an even more permissible license.
- **NEW**: Upgrade Gemoji to 3.0.1.
- **NEW**: `version` and `version_info` are now accessible via the more standard form `__version__` and `_version_info__`. The old format, while available, is now deprecated.
- **FIX**: Fix GitHub emoji CDN links to use their latest.
- **FIX**: Fix issue where entities in the form `&35;` would trigger MagicLink's shorthand for issues.
- **FIX**: Don't install tests when installing package.
- **FIX**: Fix for BetterEm case `**Strong*em,strong***`.
- **FIX**: Fixes for non-word character boundary cases in BetterEm, Caret, Mark, and Tilde extensions.
