Certification

• I certify I am an Epic Owner for Kubeflow Notebooks 2.0 and expected to create planning-related issues.

Description

Description
In kubeflow/kubeflow, the process for releasing was the following:

1. Update the releasing/version/VERSION file
2. Run the update-manifests-images script to use the defined tag (which, manually, was the same as VERSION)

Then, once a PR with both changes is raised, the images will have a tag defined in VERSION, and the manifests will be updated to use these images.

We'll need a similar script to ensure we can have a release for the components.

Implementation
We can copy-paste the script from the kubeflow/kubeflow repo and only keep the migrated components.
update-manifests-images

We'll need to ensure that once the script is run, all the expected manifest tags are updated.

Acceptance Criteria

1. Create the Script + VERSION file.
2. The script is runnable.
3. All the expected manifest tags are updated.
