refactor: remove outdated function exercises and update package-lock

- Deleted the `02.problem.parameters-and-returns` exercise and its associated files, including index.ts, package.json, and README.
- Added new entries for `02.problem.parameters` and `02.solution.parameters` in package-lock.json to reflect the updated structure.
- Marked certain entries as extraneous to clean up the dependency tree.
