fix: make configuration file readable only to the user who create it (#117)

When the `vt init` command is run, configuration file `.vt.toml` is created. This file was created with permissions 0666, who allowed everyone to read it. With this change the file is created with permissions 0600, so that only the user who created can read it or write it.
