Description

Newlines existing in the middle of a style definition for LESS files should be catch. Currently, Magento2/Sniffs/Less/ColonSpacingSniff.php has this checking in place but it is not working, as PHPCS strips newlines that goes in the middle of a sentence.

Expected behavior

Being able to catch the following case

.foo { bar: 'xyz'; }

Benefits

An incorrect LESS formatting would be catch
