Update R CMD Check GitHub Action

[VisruthSK]

Summary

Fix failing R CMD Checks by swapping to r-lib GHA steps to handle sys/R dependency resolution. Also moves from bespoke steps to r-lib or native GHA steps/config.

For Ubuntu with R 3.6, since the suggested package randomForest requires 4.1, this PR selectively deletes lines in the action to not need randomForest (in example and DESCRIPTION). Pipes in tests are also removed to run on R 3.6

@paul-buerkner Dependency resolution fails on Ubuntu 3.6 since a minimum version of randomForest is pinned which requires R 4.1 (see logs). Can the versioning constraint on randomForest be relaxed? Could vignettes be skipped on 3.6?

You can just merge these github action PRs without my checks if you have the github permissions for that
