Fix output from gitops to use "fleets" instead of "teams", "queries" instead of "reports"

[sgress454]

Related issue: Resolves #40621

Details

This PR updates the output from fleetctl gitops and fleetctl apply to use the correct terminology:

• "fleet" instead of "team"
• "report" instead of "query" (where appropriate)
• "for unassigned hosts" in place of "No Team" where possible, and "for fleet Unassigned" otherwise.

All changes other than tests are in client.go and are text-only; no functional code is changed (and no code relies on the strings besides tests).

Testing

• Added/updated automated tests
• QA'd all new/changed functionality manually

I did a fleetctl generate-gitops and a fleetctl gitops run and saw the updated logs:

[+] would've applied EULA
[+] would've applied certificate authorities
[+] would've applied fleet config
[+] would've applied MDM profiles
[+] would've applied enroll secrets
[+] would've applied 1 report
[+] would've applied 1 software package for fleet 'Unassigned'
[+] would've applied 0 app store apps for fleet 'Unassigned'
[+] would've applied webhook settings for unassigned hosts
[+] would've applied 1 policy
[!] gitops dry run succeeded

but I did not go through and try and replicate every log or error message. I think the best we can do on this one is eyeball the code changes for mistakes.
