Improve gitops dry run logging for query deletion

[williamtheaker]

Current fleetctl gitops --dry-run output:

[+] would've applied fleet config
[+] would've applied enroll secrets
[+] syncing 3 policies
[-] would've deleted policy foo
[-] would've deleted policy bar
[-] deleting 2 policies
[+] syncing 1 queries
[-] deleting query foo
[-] deleting query bar
[-] deleting 2 queries
[!] gitops dry run succeeded

^ It's not really deleting queries in a dry run, but the output can be alarming if you're not paying close attention.

Less scary/more accurate output for queries:

[+] would've applied fleet config
[+] would've applied enroll secrets
[+] syncing 3 policies
[-] would've deleted policy foo
[-] would've deleted policy bar
[-] deleting 2 policies
[+] syncing 1 queries
[-] would've deleted query foo
[-] would've deleted query bar
[-] deleting 2 queries
[!] gitops dry run succeeded
