Composer: raise the minimum supported PHPCS version to 3.13.4

This is necessary to benefit from the new way to tokenize fully qualified `\false` and `\null` introduced in 3.13.3 (PHPCSStandards/PHP_CodeSniffer 1206). It will simplify a fix for how `WordPress.WP.EnqueuedResourceParameters` handles fully qualified `\false` and `\null` (see 2630).

Bumping the version to 3.13.4 instead of 3.13.3 as 3.13.4 contains a fix to a bug that affected 3.13.3 that prevents WPCS sniffs tests from executing (PHPCSStandards/PHP_CodeSniffer 1213).
