Summary

Backport #34440 to LTS 1.13.x.

Adding files from an online_drive datasource (e.g. SharePoint, OneDrive) in a published Knowledge Pipeline fails with a 500, because DataSourceType has no ONLINE_DRIVE member and the documents.data_source_type enum check rejects the insert:

ValueError: <DatasourceProviderType.ONLINE_DRIVE: 'online_drive'> is not a valid DataSourceType

The fix was cherry-picked to the hotfix/1.13.3-fix* branches but never reached lts/1.13.x. No migration is needed; the column is VARCHAR and the enum is validated in the application layer.

Source: #34440
Source commit: 993a301

Verification

• Cherry-pick applies cleanly on lts/1.13.x.
• pytest tests/unit_tests/core/app/apps/pipeline/test_pipeline_generator.py: 20 passed. Without the enum change, the new test fails with the error above.
• ruff check and ruff format --check pass on the changed files.
