fix: sort provisioner key tags in cli output (#14875)

I'm seeing flakes like

```
    provisionerkeys_test.go:68: 2024-09-30 05:58:44.686: cmd: matched newline = "CREATED AT            NAME          TAGS            "
    provisionerkeys_test.go:72: 2024-09-30 05:58:44.686: cmd: matched newline = "2024-09-30T05:58:44Z  dont-test-me  my=way foo=bar  "
    provisionerkeys_test.go:74: 
        	Error Trace:	/Users/runner/work/coder/coder/enterprise/cli/provisionerkeys_test.go:74
        	Error:      	"2024-09-30T05:58:44Z  dont-test-me  my=way foo=bar  " does not contain "foo=bar my=way"
        	Test:       	TestProvisionerKeys/CRUD
```

e.g.
https://github.com/coder/coder/actions/runs/11100237276/job/30835714478?pr=14855

Since the tags are a map, we weren't outputting them in a consistent
order on the CLI, leading to flakes.

This sorts the tags by key when converting to a string, for a
consistent, canonical output.
