I'm not sure if we still need to exclude the FirstExpressionLine if multi-line if-statements are formatted following PSR-12 regardless, e.g.

// PSR-12:
// Expressions in parentheses MAY be split across multiple lines, where each subsequent line is indented at least once.
// When doing so, the first condition MUST be on the next line.
if (
 $firstExpression ||
 $secondExpression ||
 $thirdExpression
) {
 // Do something
}

But this is not blocking for me.

As per #6, we have to two inherited rulesets in YouweMagento2, which conflict with each other.

• Youwe pulls in PSR12.ControlStructures.ControlStructureSpacing
• Magento2 pulls in PSR2.ControlStructures.ControlStructureSpacing

This pull request removes the PSR-2 rule; the PSR-12 rule is still in this standard.
