Update prefetch.mdx to use more technically correct language (discord username finjo)

[finleyjb]

Description

Maybe this splitting hairs, but the existing page says that it works for links to the same site. This is not technically correct, because same-site URLs will work on different subdomains. If this does not work on different subdomains, it's technically same-origin rather than same-site.

Hi, thanks for taking the time to submit a PR but I'm not sure what this is supposed to fix...

Astro’s prefetching uses <link rel="prefetch"> if supported by the browser, and falls back to the fetch() API otherwise.

See: https://docs.astro.build/en/guides/prefetch/#browser-support

And according to MDN:

<link rel="prefetch"> is used for same-site navigation resources, or for subresources used by same-site pages.

So, according to your link... your fix (same-origin) would be wrong?

[finleyjb]

Oh interesting. You're right. I was trying it out for a link from my domain welcomehome.city to a subdomain blog.welcomehome.city. Didn't seem to work. Maybe I'll give it another shot.
