"CRAN" test script fails on GitHub action runners

Warning in url(sprintf("%s/%s", cran, path), open = "rb") :

Test runs fine locally so am assuming its some sort of network issue between GHA and CRAN. Perhaps there is something we can conditionally disable in the flags when running on GHA ?

@gowerc https://p3m.dev/cran/__linux__/noble/latest/src/contrib/Meta/current.rds does not actually exist when I try to access it from my browser either?

[gowerc]

Interesting... thats not from our code is it though ? Isn't that from R CMD check ? Is there any options to disable that specific check (what even is it)?

@gowerc might be an issue with the image / using p3m, see:

• cannot open URL in check --as-cran rocker-org/rocker-versioned2#532
• https://forum.posit.co/t/404-error-during-devtools-check/166426/8

Apparently the scripts run with sh (dash on Ubuntu) rather than bash, I will also take a shot at converting to that and robustifying

@gowerc since #553 is now merged, this can be closed, I think?
