Subject: [PATCH] docs(1.x/concepts/islands): fix dead deno.land/x/fresh
 IS_BROWSER doc link
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

`https://deno.land/x/fresh/runtime.ts?doc=&s=IS_BROWSER` (404) — the
`deno.land/x/*` docs URL pattern was retired when Deno moved module
documentation to JSR.

Replaced with the canonical JSR module page:
`https://jsr.io/@fresh/core` (200).
