Remove gts/gjs from eslint-disable-task glob since babel parser does not support it

• Fixes https://github.com/checkupjs/checkup/issues/1347 which has more info
• gjs/gts files requires using the eslint-plugin-ember eslint plugin to do the preprocessing for <template> tags
• The task eslint-summary-task uses the eslintrc file so it works as expected
