Description of changes

A few days late, but here are the highlights of January:

• improve docs in rehype, importantly rehype-minify, update sponsors everywhere
• clean some last stuff in MDX (custom elements, webpack loader cache, publishing docs)
• improve formatting of JSX (https://github.com/syntax-tree/mdast-util-mdx-jsx/releases/tag/2.0.0), add a base to build prose wrapping while formatting on (https://github.com/syntax-tree/mdast-util-to-markdown/releases/tag/1.3.0)
• some unified-language-server improvements: unifiedjs/unified-language-server@f222a65, unifiedjs/unified-language-server@711e692, unifiedjs/unified-language-server@2859d30.
• released MDX 2! (on feb 1 though)

For Feb: start looking at Rust, look through (tough) existing issues such as (emphasis) formatting
