Description
This PR removes an if condition to maintain backwards compatibility that is no longer needed. It was added via squizlabs/PHP_CodeSniffer@4982619 to preserve backwards compatibility back in a time when it was possible to programmatically set ignore patterns using
CodeSniffer::setIgnorePatterns()
(see https://pear.php.net/bugs/bug.php?id=19859). This method was removed a long time ago via f61025c#diff-c36ecedca179eab0b3cd245e872a96ab26fa08e567437e167f4eda1779c15c89L431-L435, and since then, there is no way for users to set the ignore pattern array with numeric indices.Suggested changelog entry
