Currently Report Portal launches have the name of the Konflux pipeline that generated them.

To get to the original GitHub PR one has to:

1. Pick a Report Portal launch
2. Check which component is testing
3. Pick the right one among these and navigate to "Pipeline runs"
4. Copy the pipeline_name tag and search it among the pipeline run
5. Once found, click on the run
6. There you can find the commit the run is referring to
7. Clicking on that and scrolling to the bottom, you can find the link to the PR

We want a convenient way to link directly a launch to the PR it comes from (if it exists).

That can be achieved leveraging a combination of Data Router tags and context information in the Konflux pipeline, similar on how it is done for the Konflux pipeline name.

Acceptance Criteria:

• Every component test launch that is generated from a PR must have a link to that in its tags.
• The existing capabilities of the test reporting are not affected.
