frontmatter is not a function

[shedali]

testing out micromark-extension-frontmatter, following the readme on the repo

When I first run it, I get the error:

TypeError: micromark_extension_frontmatter_1.frontmatter is not a function

Repro here: https://stackblitz.com/edit/node-rp4sym?file=index.js

Readme and code was recently updated for ESM, which is shipping soon, but not yet released (first want to do some more changes in micromark).
Assuming you can use ESM without problems, then you should be able to for now use:

import frontmatter from 'micromark-extension-frontmatter'

In a couple of days, after updating everything, it would be as what’s now in the readme!

The previous readme documents the currently published code. The current code is still requirable, the next code will have to be imported

just confirmed that works, thanks :)
