Documentation Page and Sharing Improvements

[jjoderis]

Summary

Addresses some none blocking requests for changes from #265.

Added some error messages for situations where the sharing logic might throw errors (e.g. network problems) and refactored the documentation page to fetch some data using react query

Details

• Added error messages to the share modal function that change the sharing state and might run into errors when communicating with the backend
• refactored the documentation page code by separating the user workspace code and components into a new file
• using react query to fetch the workspaces from the backend and a suspense boundary to wait for the fetch to finish to improve on the current logic
• fixed the suspense logic in the process list sidebar bpmn preview to not stall the page while the bpmn is fetched
• Removed some unused code from process-info-card.tsx
