MVP - Adapting the PR test

[vcerenu]

Description

The current Kubernetes test only uses images hosted on Docker Hub, so the workflow needs to be adapted so that it can test from images hosted on ECR, where the development images will be uploaded.

In addition, the deployment needs to be adapted to the changes that are going to be made to the repository for v5.0.0, adding the necessary dependencies and trying to obtain the correct images according to the status of the branch we are testing at that time.

Tasks

• Add the use of ECR ​​images in the test
• Verify the correct deployment with development images
