Update index.js – Removed deprecated 'line' from utils.report

Removing deprecated 'line' from utils.report.

"Stylelint: (notice:6847)[stylelint:D07]DeprecationWarning: Providing the line argument in the util.report() function is deprecated ("plugin/selector-bem-pattern")."

This resolves #76. But you need to specify index and endIndex instead of line as per the following message.

Please pass both index and endIndex as arguments in the utils.report() function of “plugin/selector-bem-pattern” instead.

@akiomik – thanks for the heads up.

Would passing the start and end offsets be the correct arguments to pass though?

    bemLinterWarnings.forEach(function(warning) {
      stylelint.utils.report({
        ruleName: ruleName,
        result: result,
        node: warning.node || root,
        index: warning.node.source.start.offset,
        endIndex: warning.node.source.end.offset,
        column: warning.column,
        message: warning.text + ' (' + ruleName + ')',
      });
    });
