feat: Add seed people and companies data for demo environment (#2207) (#2307)

* feat: seed companies and people data

* init DataSeedDemoWorkspaceCommand to handle:
- seedCoreSchema()
- seedMetadataSchema()

* feature: Seed workspace with demo data

- delete workspace
- initDemo() with prefillWorkspaceWithDemoObjects()

* added companies-demo.ts with data
* added people-demo.ts with data

* added workspaceId to seedFeatureFlags()

* delete previous CoreSchema before seedCoreSchema

* added workspaceMemberPrefillData

* getDemoWorkspaces() to get DEMO_WORKSPACES from config

* defined DemoSeedUserIds

- created core/demo/ to keep modified seedCoreSchema() there
- DemoSeedUserIds with new set of users and Ids

* generateOpportunities() to seed demo opportunities (limit = 50)

* Code review and fixes

* Fix
