Setting R version in action

[psychemedia]

I can successfully use the package builder action to build a wasm package, but it seems to be using 4.4 which conflicts with the v4.3 kernel used in the jupyterlite webr kernel, as per
r-wasm/jupyterlite-webr-kernel#6 (comment)

It would be useful if the build action could take an optional R version parameter and build correspondingly.

Hi,

You should be able to set the parameter webr-image: ghcr.io/r-wasm/webr:v0.3.3 in the action to build using an older webR Docker image. This older version should build packages compatible with R v4.3.* and https://webr.r-wasm.org/v0.3.3/.

Note that eventually I'll get around to updating the jupyterlite kernel for newer versions of webR. Once that's in place, you'll need to remove the webr-image parameter so that the latest webR image is used, building R v4.4.* packages.
