feat(library): Introduce R 4.3.3 as library entry

[Mihnea0Firoiu]

Introduce R helloworld example.

The Docker works as expected, with the output: [1] "Hello, World!"

Check with multiple options for the -M flag when using kraft run:

1. For no option: E machine fatally exited
2. For 256M:

   [    0.219079] CRIT: [libvfscore] Failed to extract cpio archive to /: -3
   [    0.219337] ERR:  [libukboot] Init function at 0x14adc0 returned error -5
   E  machine fatally exited

   3. For 768M:

      Rscript execution error: Function not implemented

@Mihnea0Firoiu , did you enable system calls?

I would suggest you add this as a library/ item. And when you create the Kraftfile for that (use any existing Kraftfile, i.e. Nginx, uncomment the # CONFIG_LIBSYSCALL_SHIM_STRACE: 'y' line. And that will provide you extensive info.

Also document this problem as an issue, following the others.

@razvand Should I keep the name helloworld-r for the directory when I introduce it as a library/ item or should I change it to R/4.3.3 ?
