[Feature]: clarify maxDiffPixels override in logging in case of failure

[fdm-mateco]

🚀 Feature Request

When there is a global override for maxDiffPixels, it should be mentioned in the logs when toHaveScreenshot fails, as this is what's being used. See example below.

Example

In playwright.config.ts:

expect: {
    timeout: 5000,
    toHaveScreenshot: {
      maxDiffPixels: 1
    }
  },

In a test:
await expect(locator).toHaveScreenshot('calendar.png', { maxDiffPixelRatio: 0.02 });

Currently: in case of failure, the logging will say:

Expected: the logging mentions the global override somehow

Motivation

Avoid confusion, make it clear what has actually been compared.
