Clarify relation to https://github.com/LaPreprint/typst

[talios]

A while ago I came across https://github.com/LaPreprint and liked it, but found some small issues which I raised as a PR in LaPreprint/typst#1 which doesn't seem to have had any traction.

Is this repository, which seems much more active related to the above at all, and would it be worth moving my PR changes to this version of LaPreprint?

The other repository will be treated as the source of truth and this one a copy that works with the MyST markdown templating system.

Lost the notification for the other PR, thanks for your help there, appreciate it!

@fwkoch we should update the readme to make this clear!

Excellent! Cheers.
