Undeprecate the silent parameter

### New feature, improvement proposal

After upgrading `maven-dependency-plugin`, we are getting this warning:

```
[INFO] --- dependency:3.10.0:copy-dependencies (copy-dependencies) @ app ---
Warning: Parameter 'silent' (user property 'silent') is deprecated: to be removed in 4.0; use -q command line option instead
```

This is not really helpful. Using `-q` will suppress all Maven output. Setting `silent` for one execution of the Dependency plugin will just suppress logging each copied dependency, which is a valid use case.

Start by locating the Maven Dependency Plugin handling and deprecation declaration for the `silent` parameter. Confirm how one plugin execution suppresses copied-dependency logging, then verify that the deprecation warning is gone while Maven's broader output remains unaffected.
