PSR2.Methods.FunctionCallSignature.SpaceBeforeCloseBracket false positive for heredoc/nowdoc

[mabar]

Describe the bug

PSR2.Methods.FunctionCallSignature.SpaceBeforeCloseBracket forbids space before close bracket, but it should not be reported if last value in call is heredoc/nowdoc

Code sample

This is okay

function test()
{
	foo(
		'bar',
		'baz',
	);

	foo(
		<<<'MSG'
Long
Message
MSG,
	);
}

This is reported by rule

function test(): void
{
	foo(<<<'MSG'
Long
Message
MSG,
	);
}

Custom ruleset

<?xml version="1.0"?>
<ruleset>
  <rule ref="PSR2.Methods.FunctionCallSignature.SpaceBeforeCloseBracket"/>
</ruleset>

To reproduce
Steps to reproduce the behavior:

1. Create a file called test.php with the code sample above...
2. Run phpcs test.php ...
3. See error message displayed

Expected 0 spaces before closing parenthesis; newline found (PSR2.Methods.FunctionCallSignature.SpaceBeforeCloseBracket)

Expected behavior
No error.

Interesting is that similar code without heredoc/nowdoc does not report problematic check, but instead reports PSR2.Methods.FunctionCallSignature.ContentAfterOpenBracket

function test(): void
{
	foo('bar',
		'baz',
	);
}

Reporting fixable ContentAfterOpenBracket would also work (and should be probably fixed too), because in case ContentAfterOpenBracket is fixed, then SpaceBeforeCloseBracket is no longer reported

Versions:

• OS: Windows 10
• PHP: 8.1.9
• PHPCS: 3.7.1
• Standard: orisai/coding-standard-php (but mostly irrelevant for the issue)
