Improvements to API Docs

[abidlabs]

Some small improvements to the API docs as I start to look at the clients.

Closes: #2569
Closes: #6055

Here's how it looks locally:

Here's how it looks on Spaces (note that we now use Space ID instead of the ugly replica URL):

Something isn't right?

• Maintainers can change the version label to modify the version bump.
• If the bot has failed to detect any changes, or if this pull request needs to update multiple packages to different versions or requires a more comprehensive changelog entry, maintainers can update the changelog file directly.

These links were broken but it was never reported because I don't think anyone realized that they were links in the first place. The styling does not make it very clear its a link.

I think explicitly numbering the steps makes it more inviting to users.

Thanks for the fixes @abidlabs lgtm, made one comment

[aliabd]

The font sizes are really off:

The text looks really small. and the code snippets for the libraries are too large with too much padding on the bottom. it's weird.

I suggest adding:

p {
		font-size: var(--text-lg);
	}

and modifying the .library css to be

.library {
		border: 1px solid var(--border-color-accent);
		border-radius: var(--radius-sm);
		background: var(--color-accent-soft);
		padding: var(--size-1);
		color: var(--color-accent);
		font-size: var(--text-md);
	}

looks much better:

Sorry @abidlabs not sure why you didn't include the spaces screenshot in the description, but noticed an issue (tested here using wheel from latest commit)

You need to also change {root} to {space_id || root} somewhere in CodeSnippets.svelte

Ah nice @aliabd thanks for catching both of those issues. Will fix soon

[abidlabs]

Thanks again @aliabd!
