Array standard non-conformance errors are not reported

[jaymcp]

Describe the bug
Big Bite enforce short array syntax ([]) and disallow long array syntax (array()), but this is not reported correctly.

To Reproduce
Create a PHP file containing some arrays in a mix of short and long formats. Run PHPCS against this file using our standard. No errors regarding syntax will be reported.

Expected behaviour
Arrays declared using long syntax array() should be reported as erroneous.
