Change default .scss-lint.yml location

Threw my name in there for good measure :hankey: 
@ahmednuaman sorry can't do it asap today, but regardless, I'm not sure what the correct fix should be.
Should we try to find out why scss-lint can't find the `.scss-lint.yml` which comes with the task.
Or should we remove `.scss-lint.yml` all together and change task code to not try to use --c to inject configuration when non is provided by task user.
I'm personally leaning in favor of removing it all together, but if we go this way we need to take into account that if someone has been using the default file which comes with the task and that file is different from the one that comes with scss-lint, than after upgrade they will be getting errors and warnings from validation.

WDYT ?
