There are a couple of .*-git packages installed from the AUR, like lf-git and mutt-wizard-git, but by default yay doesn't update them when updating packages, making them outdated after a while. This command edits yay's configuration to always update these packages as well if updates are available for them.
The -Y just makes sure that yay only edits the configuration file, but doesn't run an update.
