`cloud_check()` and minimal R versions

[lionel-]

Currently cloud checks is using R 4.0.3. It seems it doesn't check the minimal R requirement and I get failures like this:

Error in parse(outFile) : 
  /tmp/workdir/text2map/old/text2map.Rcheck/00_pkg_src/text2map/R/utils-embedding.R:296:6: unexpected '>'
295:     omit_empty = TRUE
296:   ) |>
          ^
ERROR: unable to collate and parse R files for package ‘text2map’
* removing ‘/tmp/workdir/text2map/old/text2map.Rcheck/text2map’

It'd probably be better to not run the checks if the R version requirement is not met?
