The virtual machines that run Github actions have lots of tools 
installed, but apparently not LaTeX.  So you need to figure out the 
"step" to install it.  I'm not currently using Rnw with Github actions, 
but by looking at the README for https://github.com/r-lib/actions, I'm 
pretty sure all you need is to add

   - uses: r-lib/actions/setup-tinytex using v1

somewhere after

   - uses: actions/checkout using master
