enable arm64 build for rocker/rstudio after RStudio IDE 2023.05.0 (#…

…651)

Close #144

Currently the linux/arm64 platform version of RStudio IDE is not bundled
Quarto CLI, but bundling may begin after RStudio IDE 2023.05.0.
(rstudio/rstudio#12411, rstudio/rstudio#13127)

When the Quarto CLI bundle to the RStudio IDE is started, I think we can
start building arm64 version of `rocker/rstudio`.

This PR also includes a small refactoring to correspond to the recently
released purrr 1.0.0. (Close #595)
