assertEquals doesn't correctly compare Blobs

[EvanHahn]

Describe the bug

assertEquals doesn't consider value-equal Blobs to be equal.

Steps to Reproduce

Run the following code:

import { assertEquals } from "jsr:@std/assert";
assertEquals(new Blob(["foo"]), new Blob(["foo"]));

Expected behavior

This should not throw an error. Instead, it throws AssertionError: Values are not equal.

Environment

• OS: macOS 15
• deno version: 2.1.0
• std version: 1.0.8
