SigmaHQ Rule Creation Conventions

• If your PR adds new rules, please consider following and applying these conventions

• Reverted back the deleted comments @frack113 as they were there in case we wanted to revert back to regex.
• I reverted some CLI rules to use regex as its much more accurate and i don't see why we don't keep them as regex anymore. Changing them to contains is basically "regex" for a lot of EDR/SIEMs

@phantinuss can you double check before i merge.

Plus of the regex is that the order or arguments is relevant, wheres with contains it's not. Can be upside or downside depending on the specific case.
