Applying the watsonx Orchestrate 5.3.1 hotfix (Hotfix 1)

#!/bin/bash
# -----------------------------------------------------------------------------
# watsonx Orchestrate 5.3.1 Hotfix
# - Verifies watsonx Orchestrate version from .status.versionStatus.status.
# - Images of Operators are replaced with the image from hotfix script.
#   * HOTFIX_LABEL_VALUE for hotfix 0 is 5.3.1.0
#   * If an existing label value matches x.x.x.x and is higher than HOTFIX_LABEL_VALUE,
#     the script exits early after informing you
# - Deletes a fixed set of Jobs in the operands namespace and waits for all to reappear with
#   new UIDs and succeed
