fix: Cypress test creating an Image without a cy-test prefixed label

[bnussman-akamai]

Description 📝

• I made a mistake in feat: [M3-8103] - Refactor Image Create and Add Tags #10471 (specifically here)
• I removed the randomLabel() from the createImage call because at the time, it didn't occur to me that the image label mattered for the sake of the test. I was correct in that sense, but I failed to remember that cypress only cleans up entities that are prefixed with cy-test 🤦 . Our test accounts are filling up with Images that are not being cleaned up as a result 😣
• This PR adds back the randomLabel() so the image is created with a label that will be cleaned up

How to test 🧪

• Verify the image created by create-stackscripts.spec.ts are prefixed with cy-test

Thanks for the catch/fix Banks! I'll take care of keeping the Images cleaned up while this makes its way into peoples branches, etc.
