Enable synchronization2 in feature chain

[Raffaello]

otherwise an error is reported

That chapter does not make use of any sycn2 features, so no need to enable that yet.

This should match what the code does instead:

vk::StructureChain<vk::PhysicalDeviceFeatures2, vk::PhysicalDeviceVulkan13Features, vk::PhysicalDeviceExtendedDynamicStateFeaturesEXT> featureChain = {
		    {},                                   // vk::PhysicalDeviceFeatures2
		    {.dynamicRendering = true},           // vk::PhysicalDeviceVulkan13Features
		    {.extendedDynamicState = true}        // vk::PhysicalDeviceExtendedDynamicStateFeaturesEXT
		};

following the tutorial, the program failed without sync2.
as it was explicitly wrote in the error message to enable it.
unless it was a bug in the validation layer.

besides i was using vulkan api 1.4 not 1.3 if it means anything.

p.s.
also there are quite few holes in the tutorial that i filled the gaps with old tutorial, it might also this one.

besides please also note that in the C++ code example: https://docs.vulkan.org/tutorial/latest/_attachments/04_logical_device.cpp

has these required extensions:

std::vector<const char *> requiredDeviceExtension = {
	    vk::KHRSwapchainExtensionName,
	    vk::KHRSpirv14ExtensionName,
	    vk::KHRSynchronization2ExtensionName,
	    vk::KHRCreateRenderpass2ExtensionName};
