[Task](ci): Move from vault-injektor to secrets-injector

[ArtieReus]

Task Description
To comply with secret rotation requirements, references to the Vault should be updated to use the Secrets Injector. This will result in a secret that can be consumed directly in Kubernetes. Once the rotation mechanism is in place, the deployment will be ready for automatic rotation.

Sub-tasks

• Change all vault references to use the secret injector.

Example:

    token: *vault(path: <path-to-the-secret>, field: <field>)
    token: vault+kvv2://secrets/<path-to-the-secret>/<field>
