asserEquals false positive: Says two equal values are not equal

[BlackAsLight]

Describe the bug
assertEquals incorrectly says the example below isn't equal and fails to actually highlight any difference between them.

Steps to Reproduce

import { assertEquals } from "@std/assert";

assertEquals(
  new File([new Uint8Array(10)], "blob", { type: "application/octet-stream" }),
  new File([new Uint8Array(10)], "blob", { type: "application/octet-stream" })
);

Expected behavior

It not say they're different.

Environment

• OS: MacOS Tahoe
• deno version: 2.6.3
• std version: @std/assert@1.0.16

[BlackAsLight]

For clarity, it only says they're different when I add the new Uint8Array(10) to them. Otherwise it has no complaints.

Dupe of #6774

It's not really possible to synchronously compare equality of contentful Blobs, of which Files are a subclass, because all the methods to read their content (text(), arrayBuffer(), bytes()) return promises.
