fix: Fix opening files on linux (#1180)

I don't know how about other OS where you using SHELL, but on linux you should
pass arguments like this, or this happens:

[src/bridge/command.rs:26] cmd = Command {
    std: "/usr/bin/nvim" "--embed README.md",
    kill_on_drop: false,
}
nvim: Unknown option argument: "--embed README.md"
