Don't add rtools in PATH as this could mess other actions like Julia

julia-actions/setup-julia@v1.9.5 is using `tar` for Windows installation
now but uses any `tar` from PATH. However, it requires a `tar.exe` that
can handle Windows paths with drive letters.

In our workflow, `tar` is found in `/usr/bin/tar` from rtools being
added to PATH. This leads to error as it does not support the drive
letters.

Not adding rtools to PATH will solve, and should not impact the workflow
as pak is used for R packages installation.
