Migration from docusaurus-preset-shiki-twoslash

Continuation of the discussion in https://github.com/shikijs/twoslash/pull/198 since that repository is archived now. What's the steps I should take to get my Docusaurus page to be compatile? All I wanted is for the font styling to be applied, I have provided a perfectly valid patch, surely it's not that hard to just push a new release to NPM.
