### What changes were proposed in this pull request? Spark 3.0 accidentally dropped R < 3.5. It is built by R 3.6.3 which not support R < 3.5: ``` Error in readRDS(pfile) : cannot read workspace version 3 written by R 3.6.3; need R 3.5.0 or newer version. ``` In fact, with SPARK-31918, we will have to drop R < 3.5 entirely to support R 4.0.0. This is inevitable to release on CRAN because they require to make the tests pass with the latest R. ### Why are the changes needed? To show the supported versions correctly, and support R 4.0.0 to unblock the releases. ### Does this PR introduce _any_ user-facing change? In fact, no because Spark 3.0.0 already does not work with R < 3.5. Compared to Spark 2.4, yes. R < 3.5 would not work. ### How was this patch tested? Jenkins should test it out.
