Consider adding {httpgd} to the set of localised packages to be installed

See here: https://renkun.me/2020/06/16/using-httpgd-in-vscode-a-web-based-svg-graphics-device/

I'd rather have this package separated as well, you can also add the required code to the .Rprofile.

Maybe there should be a parameter to choose whether to do this. use_httpgd = FALSE?
