[Typst Universe] Allow to hide some README data

[mayconfmelo]

Problem related

In my package repositories, I like to start the README.md with the package title and description; when the package is added to Typst Universe, the title is automatically stripped in favor of the Typst package name (no problem here), but other metadata stays there and can end up duplicated, like the description:

Repository	Typst Universe

Proposed solution

Everything with some specific class in README.md could be automatically hidden in Typst Universe:

<span class="universe-hide">
    Simple and complete books without introducing new syntax
<span>

This could also be useful to hide repository-specific data (such as development info) from Typst Universe.

Considered alternative

A data attribute could also be used, instead of a class:

<span data-universe-hide>
    Simple and complete books without introducing new syntax
<span>

Additional info

I did a quick search through documentation and found no such feature; if there is already any, please disregard this request.

Quick update: I was able to hide the package description only in Typst Universe using a .hidden class. It's not quite semantic, but it works...

<p class="hidden">
Simple and complete books without introducing new syntax  
</p>

I wouldn't recommend using that trick, the class name may change or be removed at any time, we don't guarantee that it will work forever.

To be honest, I'm not sure we want to provide a way to do that, I feel like it will always be a bit of a hack. The best solution in my opinion is simply to remove the sections you want to hide from the README you copy to this repository for submission. This process can probably be automated fairly easily with external tools, I'm sure you are not the first to need some kind of templating in Markdown files.

I understand that this trick is far from ideal — and in fact, it's a bit of a hack for the sake of separating GitHub and Typst Universe content.

In my case, my jusfiles are already cluttered with development code for testing, local installation, deployment to the typst/packages fork, spell checking, etc. It wouldn't be worthwhile to add even more secondary code to make the necessary changes to the README.
