Add v3 r and rstudio images with R 4.5.3 and updated packages

[remlapmot]

Paging @bloodearnest

R 4.5.3, which according to the R-Core team will be the last patch release of R 4.5 https://stat.ethz.ch/pipermail/r-announce/2026/000718.html, was released last week on the 11th March. So I'd say it makes sense to have v3 r and rstudio images including that - which is what this does (and the v2 image is about 1 year old now - which is my personal limit for R related stuff).

The v3 additions are essentially a copy of what we do for v2 with the updated R and updated CRAN_DATE:

• The updated CRAN_DATE gets us the current versions of the packages notably including ggplot2 version 4.
• In a few places I've had to generalise the code to swap a hardcoded v2 for using the MAJOR_VERSION env var.
• Comparing the number of R packages - v2 has 544 - v3 has 540 (due to different dependency requirements). I think the only notable difference is that on the new v3 CRAN_DATE the parglm R package is no longer available on CRAN https://cran.r-project.org/package=parglm, and the parglm GitHub repo has been untouched for 5 years https://github.com/boennecd/parglm, so in v3 I have replaced parglm with the fastglm package https://cran.r-project.org/package=fastglm.
• And I realised we never switched from the netlib BLAS/LAPACK to the faster OpenBLAS and its LAPACK - I've made that switch in v3 - running sessionInfo() this is reported in the following lines

• I also bumped the version of rstudio-server in v2.

As usual there was a nice summary of what's new in R 4.5 by Jumping Rivers https://www.jumpingrivers.com/blog/whats-new-r45/.

I don't believe I touched anything to do with v1 - so its epic 2hr build should still run. I have run the v2 and v3 r and rstudio builds and tests locally.

Maybe the opensafely CLI would need checking to see if it allows r:v3 and rstudio:v3?

Also - remember I have no permissions - so I can't formally 'request review' - and you'll have to trigger CI builds etc.
