Add LiteSVM Tests for Close Account (Anchor) (#470)

* feat: add LiteSVM tests for closing an account in Anchor program

* chore: update dependencies in package.json and pnpm-lock.yaml

- Add litesvm dependency with version 0.4.0
- Upgrade @solana/web3.js to version 1.98.4
- Update related dependencies in pnpm-lock.yaml to reflect changes

* refactor: clean up imports in LiteSVM test

- Anchor tests natively use Mocha, so replaced unnecessary `node:test` usage with Mocha and Chai for consistency.

* chore: update TypeScript configuration for close-account anchor

- Upgrade TypeScript compiler options to target ES2020 and use nodenext module resolution.
- Enable JSON module resolution for improved compatibility.

* fix: update LiteSVM close account test transaction instruction to match IDL

- Removed unnecessary SystemProgram reference from transaction instruction keys for clarity and correctness.

* refactor: replace `node:assert` with `chai` in tests (default for Anchor)

* chore: remove deprecated `bankrun` test
