fix(util): properly parse windows line-endings in commit messages

Due to windows line-endings `\r\n`, it would improperly split the commit
description (it failed to split at all) and cause detection of Breaking changes
to fail. The breaking changes regular expression looks to the start of the line
for the proper syntax.

Resolves: #820
