Fixes #34

Add GitHub Action to deploy PR on GitHub Pages.

* **Update `src/App.tsx`**
  - Change `BrowserRouter` `basename` prop to use `process.env.PUBLIC_URL`.

* **Modify `.github/workflows/pr-check.yml`**
  - Add permissions for `pages: write` and `id-token: write`.
  - Add step to set up Pages using `actions/configure-pages@v4`.
  - Add step to upload artifact using `actions/upload-pages-artifact@v3`.
  - Add step to deploy to GitHub Pages using `actions/deploy-pages@v4`.
