fix: using absolute paths for tsc.cmd on Windows (#30)

* fix: using absolute paths for tsc.cmd on Windows

Fix the issue with using absolute paths for `tsc.cmd` on Windows and add a test to verify the change.

* **lib/process.js**
  - Update the `spawn` function to use absolute paths for `tsc.cmd` on Windows.
  - Check for `tsc.cmd` under `node_modules/.bin` and use this path if it exists, otherwise use the global `tsc.cmd`.

* **test/index.test.js**
  - Add a test to check the `tsc` version and ensure it matches the version in `node_modules/typescript/package.json`.

* **History.md**
  - Add a new entry for the fix of using absolute paths for `tsc.cmd` on Windows.

* **.github/workflows/nodejs.yml**
  - Add a global TypeScript installation with a specific version.
