Subject: [PATCH] Fix: Explicitly install rcmdcheck in CI workflow

This commit modifies the GitHub Actions workflow to ensure the `rcmdcheck`
R package is installed reliably. Instead of relying on its inclusion in
the `r-lib/actions/setup-r-dependencies` step, `rcmdcheck` is now
installed explicitly using a dedicated `Rscript` command.

Changes in `.github/workflows/R-CMD-check.yml`:
- The `r-lib/actions/setup-r-dependencies` step is now configured to
  only install `packrat`.
- A new step `Install rcmdcheck` has been added, which runs
  `Rscript -e "install.packages('rcmdcheck', repos = 'https://cloud.r-project.org')"`.

This change provides a more direct and robust method for installing
`rcmdcheck`, which is a crucial dependency for the
`r-lib/actions/check-r-package` step. This aims to resolve the
persistent "there is no package called 'rcmdcheck'" error.
