docs: remove unnecessary call to `escapeSvelte`

[benmccann]

I had it there because it's what I've seen in all the examples around the community, but as @theetrain pointed out, I'm not sure it's actually required. From what I can tell, folks were adopting it because of https://github.com/pngwn/MDsveX/issues/212, but I can't reproduce that issue
