[MDEP-549] list deps with scope runtime should show provided scope as well

**[Sébastien Gandon](https://issues.apache.org/jira/secure/ViewProfile.jspa?name=sgandon)** opened **[MDEP-549](https://issues.apache.org/jira/browse/MDEP-549?redirect=false)** and commented

I am trying to get all the dependencies but the test ones.
I am using

```
mvn dependency:list -DincludeScope=runtime
```

in the doc the runtime scope includes **runtime** and **compile** scopes.
and it says the **compile** scope gives compile, provided, and
system dependencies
So I would expect the **runtime** scope would also return **provided** dependencies

---

**Affects:** 3.0.0

Start by reproducing `mvn dependency:list -DincludeScope=runtime` and compare its output with the documented scope rules in the Maven Dependency Plugin. Trace how the runtime scope is interpreted, then verify that provided dependencies are included while test dependencies remain excluded.
