Add OS.get_version_alias() to return a human-readable Windows/macOS version number

[Calinou]

Windows 11's major version number is actually 10.x.x, which can be confusing if you don't know about this quirk. OS.get_version_alias() avoids this by displaying the "branding" version number and the build number as a suffix, so that individual updates can still be distinguished from each other.

On macOS, OS.get_version_alias() returns the version number prepended with the version name (e.g. Sequoia for macOS 15).

On other operating systems, this returns the same value as OS.get_version().

• This closes Add OS::get_version_alias() godot-proposals#11292.

Preview

Various uses of Copy System Info when running under WINE, using winecfg to modify the Windows version reported to applications:

Godot v4.4.dev (7f5c46929) - Windows 11 (build 22000) - Multi-window, 1 monitor - Vulkan (Forward+) - dedicated NVIDIA GeForce RTX 4090 - 13th Gen Intel(R) Core(TM) i9-13900K (32 threads)
Godot v4.4.dev (7f5c46929) - Windows 10 (build 19043) - Multi-window, 1 monitor - Vulkan (Forward+) - dedicated NVIDIA GeForce RTX 4090 - 13th Gen Intel(R) Core(TM) i9-13900K (32 threads)
Godot v4.4.dev (7f5c46929) - Windows Server 2008 R2 (build 7601) - Multi-window, 1 monitor - Vulkan (Forward+) - dedicated NVIDIA GeForce RTX 4090 - 13th Gen Intel(R) Core(TM) i9-13900K (32 threads)

# The only time you'll see Windows 2.0 able to run Godot :)
Godot v4.4.dev (7f5c46929) - Windows Unknown (build 0) - Multi-window, 1 monitor - Vulkan (Forward+) - dedicated NVIDIA GeForce RTX 4090 - 13th Gen Intel(R) Core(TM) i9-13900K (32 threads)

winecfg doesn't have options to report Windows Server 2016, 2019, 2022 or 2025 as of wine-staging 9.15, so I've based the detection on this information.

TODO

• Test on macOS.
  • Is there a way to get the human-readable version directly from the OS? This way, we can support future OS versions without having to update Godot.

macOS code seems to be working as expected (only tested on current version).
