Fix scope issue in bazzite/linux immutable os

This fixes 
YARC-Official#50

In bazzite, user config folder is at $HOME/.config
Without setting requireLiteralLeadingDot to false, it requires that scopes explicitly add the ".".
Setting requireLiteralLeadingDot to false (default in linux is true), and adding "**" to the scope seems to be the only combination that i managed to get working.
