Subject: [PATCH] refactor(@schematics/angular): remove explicit strict true in
 tsconfig template for TS6 compatibility

TypeScript 6 enables strict mode by default. This change updates the workspace schematic's `tsconfig.json` template to omit `"strict": true` when strict mode is desired (relying on the default), and explicitly sets `"strict": false` when it is disabled.
