[R-SIG-Mac] Apple Silicon aka M1 Macs

[Gábor Csárdi]

One thing that I noticed both on Silicon and the intel macs at GitHub
Actions, is that the CRAN installer does not create the symlinks in
`/usr/local/bin`. Probably some permission or entitlement issue. So
you'll probably want to create them manually. E.g. on GHA it goes like
this:
