Misleading information on --set included for 'couchbase-cli backup-service repository'

In the page on 'couchbase-cli backup-service repository' under the heading 'Retrieving repository information' we include an example which does not include '–set' where the sentence prior to the example indicates it is about '–set'.

The '–set' flag is not actually valid for this command, and is instead only intended for use with 'couchbase-cli backup-service settings' which deal with settings for the Backup Service not individual backup repos.
