Update reveal-md to ES modules and updated all dependencies

[MartenBE]

This is a PR to facilitate the upgrade to Reveal.js 5.0.0 as mentioned in #462 and hakimel/reveal.js#3517 . Although Reveal.js hasn't been updated in this PR, all the rest has.

Normally, there should be no or very small breaking changes. All the unit tests and my personal use case work as expected, but I can't test everything and everyway reveal-md has been used, and many files have been edited in some way in the code base.

Martijn, you're a legend! Thanks a bunch for this 🙏

Didn't catch that we jumped to Node.js v20, tweaked that down a bit to v18 (it's not EOL).

Did a prerelease v6.0.0-next.0 with the next npm dist tag. So things can be tested and verified a bit, perhaps include reveal.js v5 as well, before we release reveal-md v6.

Wow, thanks! Didn't expect this so soon!

Unfortunately, as I posted the issue at the repo for reveal.js itself, it seems that we won't be able to call functions on the Markdown plugin anymore. We will probably have to rethink the whole render logic. I have some ideas (such as not calling the render funcxtions ourselves but transpile to https://revealjs.com/markdown/#external-markdown ), but it will take some time and experimentation to get (hopefully) something working.

PS: I also don't come from a frontend background (mainly C++ and Java), so this should definitely be tested through first by people with more uses cases.

More ideas: depending on their output, we might be able to make it easier and still hack do so using createRequire or even transform using something like jiti

That explains the typo in the title of 706394e (no worries j/k)

Again, thanks for your work, it is honestly much appreciated.

According to hakimel/reveal.js#3517 (comment) we seem to be able to use the current implementation a bit longer :) This allows us to take our time to cook up a future proof solution.
