Given I have a Secret Text credential stored in Secrets Manager (with the jenkins:credentials:type=string tag)
When I remove the type tag, and wait for the credentials cache to reload,
Then the Secret Text credential still remains in Jenkins. (It only disappears after I initiate a delete to remove the secret altogether, regardless of whether that tag was present or later removed.)

If the type tag is removed, then the credential should disappear from Jenkins when the cache is reloaded.
