Remove package-lock.json from vscode-objectql package

The vscode-objectql package had its own package-lock.json which conflicted with the pnpm workspace setup. This caused the dependency review workflow to fail.

Fix: Removed packages/tools/vscode-objectql/package-lock.json since the package is part of the pnpm workspace (defined in pnpm-workspace.yaml under packages/tools/*) and should use the root pnpm-lock.yaml instead.
