Filling in Sauce Labs test details programmatically

### What information was incorrect, unhelpful, or incomplete?

From https://github.com/mdn/content/pull/31092#issuecomment-1947640396

`sauce_google_test.js example` in the "Filling in Sauce Labs test details programmatically" section, but it looks like it's missing the `username` in the saucelabs' `updateJob()` method call and the `driver.sessionID` is undefined.

### What did you expect to see?

`updateJob()` with correct details.

Definition for `driver.sessionID`

### Do you have any supporting links, references, or citations?

There is a bit more context on where this report came from here: https://github.com/mdn/content/pull/31092#issuecomment-1960505332

### Do you have anything more you want to share?

@ShamarYarde couldn't fill this in/test this because they don't have a subscription to Sauce Labs. So that would be needed to complete this and verify it.

I'm not particularly familiar with this area. Creating this so task does not disappear
