Generic/ScopeIndent: false positive with nested closures

[jrfnl]

Describe the bug

The Generic.WhiteSpace.ScopeIndent sniff incorrectly flags code within a closure, and directly following a nested closure as having the wrong indent, while the indent is correct.

Code sample

Anonymized minimal reproduction sample:

$obj->callA($foo)
    ->callB(function (string $bar) use ($baz) {
        $joined = function (array $newParts) {
            return implode('/', $newParts);
        };

        foreach ($something as $foobar) {
            return $foobar;
        }
    })
;

To reproduce

Steps to reproduce the behavior:

1. Create a file called test.php with the code sample above...
2. Run phpcs test.php --standard=generic--sniffs=generic.whitespace.scopeindent
