A `match` statement within an `array` produces `Squiz.Arrays.ArrayDeclaration.NoKeySpecified`

[ivan-wolf]

Description
The default option of the match statement will result in the following error:
No key specified for array entry; first entry specifies key

Code sample

[
    'foo' => match ($anything) {
        'foo' => 'bar',
        default => null,
    },
];

Expected behavior
Should not result in an error.

Versions:

• OS: Ubuntu 20.04
• PHP: 8.0
• PHPCS: 3.6.2
• Standard: Squiz

Thanks for the bug report. I've added match support to the sniff and the fix will be in 3.7.0
