bug: Local docs build doesn't generate API docs for .NET 10

Two issues:

1. The build fails if sources/assets/Stride.Core.Assets/Stride.Core.Assets.csproj is present in the en/docfx.json.
2. If the above is removed, the build doesn't generate APIs docs, most likely because of the error below

Test:

docfx metadata en/docfx.json

or run run.bat, select en, select y.

Tested on my dev PC and also on clean PC with Windows 11 + VS 2026.

Error:

Identical errors listed below..

Possible issue:
All projects are pointing to sources\targets\Stride.Core.props which might be causing an issue.

Reproduce the failure with docfx metadata en/docfx.json or run.bat, selecting en and confirming the build. Start with en/docfx.json, sources/targets/Stride.Core.props, and the referenced .csproj files; done means the local documentation build completes without SDK resolver failures and generates API documentation.
