Change Impact analysis tool

Goal:
- Implement the process requirement https://eclipse-score.github.io/process_description/main/process_areas/change_management/guidance/change_management_reqs.html#gd_req__change_tool_impact_analysis
- Proposal for a solution for this was https://github.com/eclipse-score/docs-as-code/issues/314

Stakeholders:
- marco.heinemann@useblocks.com - contacted by @aschemmel-tech about the addition of a sphinx needs attribute to document the version of a needs element (to be able to link like "need_id@version") - solution implemented by UseBlocks: https://sphinx-needs.readthedocs.io/en/stable/changelog.html#release-8-0-0
- @masc2023 as the "process owner" of the change management process
