feat: Set repository root as working directory for Goose migrations in carrier-connector

- Add filepath import for path manipulation
- Calculate repository root path relative to carrier-connector location (../../)
- Set cmd.Dir to repository root before executing Goose command
- Add comment explaining directory change to locate migrations folder
- Ensure migrations can be found from carrier-connector's nested location
