Vulkan doesn't work on Windows 7 even though Windows 7 supports Vulkan 1.2!

Short description of the issue
The game fails to initialize the Vulkan renderer on Windows 7 systems that fully support Vulkan 1.2. The crash occurs because the game incorrectly enforces the VK_KHR_dynamic_rendering extension, which is missing in legacy Windows 7 drivers, preventing the Vulkan backend from loading despite meeting the base Vulkan 1.2 requirement.

Steps to reproduce the issue

1. Launch Minecraft Snapshot 26.2.1 on a Windows 7 system with a Vulkan 1.2 capable GPU (e.g., RTX 3080 Ti with driver 475.14).

2. Go to Video Settings and set "Graphics API" to "Prefer Vulkan".

3. Check the F3 debug screen.

4. Review the latest.log file.

Expected result
The game successfully initializes the Vulkan backend since the system meets the officially stated Vulkan 1.2 requirement. The F3 screen should display Vulkan instead of OpenGL.

Actual result
The game fails to create the Vulkan backend with a BackendCreationException: Device missing capabilities error. The latest.log shows that [NVIDIA GeForce RTX 3080 Ti] does not support required extensions, missing: [VK_KHR_dynamic_rendering]. The game falls back to OpenGL.
