fix: WhiteSpace\OperatorAndKeywordSpacingSniff - conflict with declare statement since PHP_CodeSniffer 3.9.1

PR PHPCSStandards/PHP_CodeSniffer#289 changes a lot around operator sniff, and now declare statement must be omitted (as it was done also for PSR-12 rule there). There is another sniff to verify declare statement, and we do not want to check it here.
