Point canonical upstream URL to this project

The new REPO_REFERENCE.md declares https://github.com/dcp6/FinCorp as the canonical upstream, but the repository content is for MakingMagicMeetups (for example making-magic-meetups/package.json has name makingmagicmeetups), so contributors or tooling that trust this reference will be directed to a different codebase. Please update this URL to the actual upstream for this repo to avoid misrouting future sync/automation workflows.
