kubectl: 'apply view-last-applied' must not use printf() semantics

**What this PR does / why we need it**:
This fixes `kubectl apply view-last-applied` to not use `fmt.Fprintf()`, as this will cause format codes in the YAML/JSON to be interpreted. For example, if a resource manifest contains `%r`, this would cause `view-last-applied` so print `%!r(MISSING)`.

**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes #45608.

**Special notes for your reviewer**:

**Release note**:

```release-note
Fixes an edge case where "kubectl apply view-last-applied" would emit garbage if the data contained Go format codes.
```
