feat(version): support nvchecker keyfile from user config home

This adds support for global keyfile from the user config home
XDG_CONFIG_HOME which allows to set tokens for GitHub and GitLab for
certain nvchecker configuration.

When ~/.config/nvchecker/keyfile.toml exists, it will automatically be
appended as keyfile of the local .nvchecker.toml file.
