// If the IDE2 is running on Linux, and the `XDG_CONFIG_HOME` variable is not available, set it to avoid the `undefined` folder.
// From the specs: https://specifications.freedesktop.org/basedir-spec/latest/ar01s03.html
// "If $XDG_CONFIG_HOME is either not set or empty, a default equal to $HOME/.config should be used."
