Update UI5 Web Components

[andreaskienle]

We reverted (PR #372) a previous Renovate update (PR #367) of the UI5 web components because of issues with the deletion dialog (issue #356). The issue appeared with this UI5 WebC update.

Tasks

• Fix the deletion dialog issues (delete project, delete workspace, delete MCP)
• Update the UI5 web components
• Can we add a test?
