fix(QTDI-2261): fix publication of dependency reports

[thboileau]

Requirements

• Any code change adding any logic MUST be tested through a unit test executed with the default build
• Any API addition MUST be done with a documentation update if relevant

Why this PR is needed?

The Jenkins build generates reports about dependencies through two maven plugins: versions:dependency-updates-report and versions:plugin-updates-report. Both generate report in target/reports.
The next step in Jenkins build tries to gather the reports in the target/site which is a mistake.

What does this PR adds (design/code thoughts)?

Fix the path where the reports are located.

Here is Jenkins job for testing the reporting https://jenkins-connectors.rnd-ci.cloud.talend.com/job/component-runtime/job/build/job/PR-1168/2/

and to be honest, it's "chore", because we don't fix anything production related
