[TypeDeclarationDocblocks] Handle multiple objects on AddReturnDocblockDataProviderRector

[samsonasik]

it currently only got last objects, which cause phpstan notice:

Generator expects value type array<int, array<DateTimeImmutable|string>>, array<int, array<int, DateTime|string>> given.

It seems there is bug on TypeFactory and TypeHasher

rector-src/src/NodeTypeResolver/PHPStan/Type/TypeFactory.php

Lines 195 to 211 in 76dc419

	private function unwrapConstantArrayTypes(ConstantArrayType $constantArrayType): array
	{
	$unwrappedTypes = [];
	$flattenKeyTypes = TypeUtils::flattenTypes($constantArrayType->getIterableKeyType());
	$flattenItemTypes = TypeUtils::flattenTypes($constantArrayType->getIterableValueType());
	foreach ($flattenItemTypes as $position => $nestedFlattenItemType) {
	$nestedFlattenKeyType = $flattenKeyTypes[$position] ?? null;
	if (! $nestedFlattenKeyType instanceof Type) {
	$nestedFlattenKeyType = new MixedType();
	}
	$unwrappedTypes[] = new ArrayType($nestedFlattenKeyType, $nestedFlattenItemType);
	}
	return $unwrappedTypes;

Fixed 🎉

@TomasVotruba I updated to use 77 as max length union to show the fix, otherwise, it just \Iterator<mixed> for this fixture test

https://github.com/rectorphp/rector-src/pull/7298/files#diff-2a2097385262575254922102ea5d5304cc01549cfcbdc51ef87c240199f2c4d5

The fix for this case is loop when inner is ConstantArrayType too.

This might be tricky to keep in readable line. The longer the docblock will be, the more mess might get int. But let's give 77 a try.

[samsonasik]

this loop again to make result of inner constant array to avoid just added the last one,

All checks have passed 🎉 @TomasVotruba I am merging it ;)
