Describe the bug
Plugin does not resolve env vars to determine path.

If I hardcode the sonar.dependencyCheck.htmlReportPath as /runner/_work/MyProject/MyProject/build/reports/dependency-check-report.html then everything works as expected.
But I need to set the path in such a way that it works for all my projects, so I tried configuring the path in SonarQube like this:

${{github.workspace}}/build/reports/dependency-check-report.html
${GITHUB_WORKSPACE}/build/reports/dependency-check-report.html
${DEPENDENCY_REPORT_PATH}/dependency-check-report.html

But none of those worked.

I also tried setting the path via systemProp.sonar.dependencyCheck.htmlReportPath in gradle.properties

However, I have confirmed that it is the correct path, since I have an upload artifact step that uses that same path.

To Reproduce
Github Actions workflow steps:

      - name: Prepare dependency report
        run: ./gradlew dependencyCheckAggregate

      - name: Upload dependency check results
        uses: actions/upload-artifact@master
        with:
          name: dependency check reporty
          path: ${{ github.workspace }}/build/reports

      - name: Build and analyze
        env:
          SONAR_TOKEN: ${{ secrets.SONAR_TOKEN }}
          SONAR_HOST_URL: ${{ secrets.SONAR_HOST_URL }}
          DEPENDENCY_REPORT_PATH: "${{ github.workspace }}/build/reports"
        run: ./gradlew build sonarqube -x test --info

Current behavior
Error: No HTML-Report found. Please check property sonar.dependencyCheck.htmlReportPath

Expected behavior
It should resolve the env var and find the file
