Install only 64-bit on R-devel Windows

[yutannihilation]

It seems the R-devel stopped providing 32-bit binaries for Windows. Accordingly, installing both arch is now problematic as it will make R CMD check run as multiarch by default unless --no-multiarch is specified, whereas 32-bit binaries are not available. So, I think setup-r action should install only 64-bit when the version is devel (though I don't find the option for this yet).

Here's the error I got when I run R-devel GitHub Action.

 ** running tests for arch 'i386' ...

  Running 'testthat.R'

 ERROR

Running the tests in 'tests/testthat.R' failed.

Complete output:

  > library(testthat)

  Error: package 'testthat' is not installed for 'arch = i386'

  Execution halted

** running tests for arch 'x64' ...

  Running 'testthat.R'

 OK

It seems this is resolved now 🎉 (maybe on R-devel's side?). Closing.
