docs: remove external project references from documentation

Cleaned up public documentation to remove references to external projects (Workshop). Documentation should be project-agnostic and professional.

Changes:
- docs/guides/import-progress-examples.md: Changed "Workshop team problem SOLVED" to "Problem SOLVED"
- docs/guides/standard-import-progress.md: Changed "Workshop team (and any developer)" to "Developers"
