Fixed Single Blog Page

Totally forgot to update the single blog post page. I didn't realize that Neocities would post a screenshot of a page I didn't link to. That's fixed now.

I also added slugify to the path names. In my src/blog folder there's a blog.11tyData.json file that looks like this:

{
	"tags": ["post"],
	"layout": "base.njk",
	"permalink": "/blog/ { { title | slugify } }/"
}

permalink and the slugify is the key.
