[Feature Request] Add info for the Winget package.

[DandelionSprout]

Is your feature request related to a problem? Please describe.
I've added a Winget package for DirectX Shader Compiler (microsoft/winget-pkgs#325910, and since Winget is also a Microsoft tool (like what Nuget is), I presume that info on that package should be added to the listed available installation methods in this repo.

Describe the solution you'd like
Presumably that mentions of the Winget installation method gets listed in the Releases notes, like what the Nuget methods are.

For the newest version at the time of writing, this would likely mean replacing:
"This DX compiler release is also available as a NuGet package Microsoft.Direct3D.DXC."

With:
"This DX compiler release is also available as a NuGet package Microsoft.Direct3D.DXC, and as a Winget package Microsoft.DirectX.ShaderCompiler."

Describe alternatives you've considered
That mentions of Winget, Nuget, binary, and other (if any) installation methods get added to the README.md.

Winget packages are unfortunately not inherently auto-updated when new binaries are released on GitHub, but there's at least a few people on the Winget-pkgs repo to ask for help on adding it to their auto-update bots or about other ways of auto-updating.
