Feature description

Currently It seems that rustaceanvim does not support expanding variables in VSCode settings. For example this is a part of the generated VSCode setting in the rust project:

{
    "rust-analyzer.rustfmt.overrideCommand": [
        "${workspaceFolder}/build/host/rustfmt/bin/rustfmt",
        "--edition=2021"
    ],
    "rust-analyzer.procMacro.server": "${workspaceFolder}/build/host/stage0/libexec/rust-analyzer-proc-macro-srv",
    "rust-analyzer.procMacro.enable": true
}

rustaceanvim loaded the settings successfully but rust-analyzer is looking for proc-macro server in a directory literally called ${workspaceFolder}/..., so I have to edit the path and ensure that my pwd is the project root.

Would you like to support this in rustaceanvim?
