feat: astro-3.0 and all dependencies updated

[Luks17]

closes #111

Description: This PR aims to be a simple port of astro-paper to Astro 3.0, no new features introduced in that update were added. A lot of styles were broken in the update, so this PR also fixes them.

Apologies if dumb question: is there a way to sort out the deprecation warnings I assume your getting in [ogTitle].svg.ts for returning a simple object etc ?

I purposefully avoided fixing that because I did not find it on the changelog and didn't want to break it. However, I just found it documented at the very end of the page, so will try to fix it later.

Should be solved now

Works for me, I think there might have been another warning in rss.xml.ts, but i've modified/forked my original and since then done other things. So I think that one might need something too?

return new Response(JSON.stringify(rss({
    title: SITE.title,
    description: SITE.desc,
    site: SITE.website,
    items: sortedPosts.map(({ data }) => ({
      link: `posts/${slugify(data)}`,
      title: data.title,
      description: data.description,
      pubDate: new Date(data.pubDatetime),
    })),
  })));

I truly appreciate your PR and your dedication to this. Thank you for your hard work.

I've also been working on the same issue locally, and I noticed that many of the changes in your PR are similar or identical to what I've been working on. If there are any changes, features, or bug fixes that you've made, which are not present in my PR, would you be open to merging them into my PR?

That will also be added soon. In the meantime, if you'd like, you can start experimenting with the new version on your own by examining the commit history, such as this PR or mine.
