Undici's fetch with integrity option is too lax when algorithm is specified but hash value is in incorrect

Details

### Impact

If an attacker can alter the `integrity` option passed to `fetch()`, they can let `fetch()` accept requests as valid even if they have been tampered.

### Patches

Fixed in https://github.com/nodejs/undici/commit/d542b8cd39ec1ba303f038ea26098c3f355974f3. Fixes has been released in v5.28.4 and v6.11.1.

### Workarounds

Ensure that `integrity` cannot be tampered with.
