[SPARK-32493][INFRA] Manually install R instead of using setup-r in GitHub Actions

This PR proposes to manually install R instead of using `setup-r` which seems broken. Currently, GitHub Actions uses its default R 3.4.4 installed, which we dropped as of SPARK-32073.

While I am here, I am also upgrading R version to 4.0. Jenkins will test the old version and GitHub Actions tests the new version. AppVeyor uses R 4.0 but it does not check CRAN which is important when we make a release.

To recover GitHub Actions build.

No, dev-only

Manually tested at #15

Closes apache#29302 from HyukjinKwon/SPARK-32493.
