Using Maven logging for `help:active-profiles` output

### New feature, improvement proposal

Current:
```
[INFO] --- help:3.5.1:active-profiles (default) @ my-project ---
[INFO]
Active Profiles for Project 'acme:my-project:jar:1.0':

The following profiles are active:

- default-repositories (source: external)
- ... [FURTHER OUTPUT ELIDED]

```

I'd rather this plugin writes to stdout using Maven's own logging facility, and ideally with concision and no repetition:
```
[INFO] --- help:3.5.1:active-profiles (default) @ my-project ---
[INFO] Active Profiles for Project 'acme:my-project:jar:1.0':
[INFO] - default-repositories (source: external)
[INFO] ... [FURTHER OUTPUT ELIDED]
[INFO]
```

Start at the help:active-profiles goal and trace how its output is emitted. Compare the current and proposed examples, then verify that the goal uses Maven's logging format with concise, non-repeated lines and that its output remains complete.
