Describe the bug

When attempting to delete a credential of type SAML through the API, the following error message is returned:

{"error":{"code":400,"status":"Bad Request","request":"f1e10825-b0e8-98a0-94b6-f42a93d6cfad","reason":"Credentials type saml cannot be deleted.","message":"The request was malformed or contained invalid parameters"}}

This seems like a bug, but may have been intentional. It's not a huge issue for us, but it seems like strange behavior to not allow deletion for some known credentials.

Relevant Kratos code

Open to putting in a PR for this if you think it's relatively straightforward.

Reproducing the bug

1. Add SAML credential
2. Try to delete SAML credential through the DELETE /admin/identities/{id}/credentials/{type} endpoint
