"Found 0 vulnerabilities in project" message does not tell how many artifacts have been scanned

**Describe the bug**
After update from Gradle plugin version 6.4.1.1 to 8.2.1 for some reason all previously reported vulnerabilities disappeared. In the build log the message
```
[16:51:59] : [Step 5/6] > Task :modules:test-external-dependencies:dependencyCheckAnalyze
[16:51:59] : [Step 5/6] Generating report for project test-external-dependencies
[16:52:00] : [Step 5/6] Found 0 vulnerabilities in project test-external-dependencies
```
appeared.

Unfortunately, from this message one cannot know if there are no vulnerabilities (which I doubt) or if no vulnerabilities have been found because nothing has been scanned (e.g. due to a misconfiguration of the plugin).

**Version of dependency-check used**
The problem occurs using version 8.2.1 of the gradle plugin.

**Expected behavior**
The plugin should not only report how many vulnerabilities have been found, but also how many artifacts have been scanned.
