[R][CI] Use rocker/r-ver instead of library/r-base #40323
Description
Describe the enhancement requested
Switch our runs of library/r-base images to rocker/r-ver. It turns out that library/r-base (and rocker/r-base) are intended to be more bleeding edge than we realized and are sometimes built against debian unstable package channels. This can cause transient package version collisions which aren't relevant to us (and cause false positive failures we need to investigate).
From https://github.com/rocker-org/rocker?tab=readme-ov-file#base-docker-containers:
| image | description |
|---|---|
| r-base | Current R via apt-get with debian:testing & unstable repos |
| r-devel | R-devel added side-by-side onto r-base (using alias RD) |
| drd | lighter r-devel, built not quite daily |
| r-ver | Specify R version in docker tag. Builds on debian:stable |
