PHP 8.0 | Squiz/DisallowMultipleAssignments: correct errorcode for as…

…signment in match expression

The `Squiz.PHP.DisallowMultipleAssignments` sniff differentiates in the error code between "normal" assignments which aren't the only thing on a line and assignments in control structure conditions.

This adds `match` to the list of control structures, so it gets the correct error code.

Includes unit test.
