We were passing a hash when the method definition expected keyword
arguments, and so we were getting warnings in Ruby 2.7:
```
db/dev_seeds/widgets.rb:11: warning: Using the last argument as keyword
parameters is deprecated; maybe ** should be added to the call
db/dev_seeds/widgets.rb:23: warning: Using the last argument as keyword
parameters is deprecated; maybe ** should be added to the call
db/dev_seeds/widgets.rb:35: warning: Using the last argument as keyword
parameters is deprecated; maybe ** should be added to the call
db/dev_seeds/widgets.rb:47: warning: Using the last argument as keyword
parameters is deprecated; maybe ** should be added to the call
db/dev_seeds/admin_notifications.rb:3: warning: Using the last argument
as keyword parameters is deprecated; maybe ** should be added to the
call
db/dev_seeds/admin_notifications.rb:11: warning: Using the last argument
as keyword parameters is deprecated; maybe ** should be added to the
call
db/dev_seeds/admin_notifications.rb:19: warning: Using the last argument
as keyword parameters is deprecated; maybe ** should be added to the
call
db/dev_seeds/admin_notifications.rb:27: warning: Using the last argument
as keyword parameters is deprecated; maybe ** should be added to the
call
```
Converting the hash to keyword arguments solves the issue.
