Add LiteSVM tests for the Processing Instructions anchor program (#478)

* feat: add LiteSVM test for processing instruction anchor program

* chore: update package dependencies and remove unused packages

- Added `litesvm` dependency to `package.json` and updated `pnpm-lock.yaml`.
- Removed `anchor-bankrun` and `solana-bankrun` dependencies from both files.
- Updated `@solana/web3.js` version in `pnpm-lock.yaml` to include a new version.

* chore: update TypeScript module resolution in tsconfig.json

- Changed module resolution from "commonjs" to "nodenext" in tsconfig.json for better compatibility with modern Node.js features.

* chore: remove unused bankrun test file

- Deleted the bankrun.test.ts file as part of the cleanup process to eliminate unused tests and dependencies.
