bug: Invalid configuration keys in readEcrConfig

[gePower]

📜 Description

The current keys used to read the ECR configuration do not match the documentation.

👍 Expected behavior

When maxImage is configured as 10, the backend should return exactly 10 images.

👎 Actual Behavior with Screenshots

The backend ignores maxImage: 10 and returns 100 images instead of 10

👟 Reproduction steps

aws:
  ecr:
    maxImages: 10
