This migration updates the filter operand values of the workflowVersion
and workflowRuns in order to capitalize them as they should be (the
product works with both deprecated camel case and capitalized). But that
may involve thousands of workflowRuns!
Let's update the command to only update workflowVersion, and update the
cleanWorkflowRuns job to remove workflow runs that are more than 14 days
old.
This way after the command is run, all new workflow runs will have the
new value for the filter operand, and after fourteen days there will be
no trace of the workflow runs with the deprecated filter operand.
