Update JsonSchema.Net.Generation to 5.0.4

[matouskozak]

Summary

Update JsonSchema.Net.Generation from 5.0.1 to 5.0.4. Keep JsonSchema.Net at 7.3.4.

Version 5.0.1 was unlisted because it declared an incorrect minimum dependency of JsonSchema.Net 1.0.0. Version 5.0.2 corrected that dependency to 7.3.4. See json-everything/json-everything#894.

Use 5.0.4, as suggested in review, to also include the fixes for properties hidden with the C# new keyword (5.0.3) and schema-definition name collisions (5.0.4). Version 5.0.4 supports the same target frameworks and requires the same minimum dependency versions as 5.0.2. See the upstream release notes.

The published ML.NET GenAI packages already require JsonSchema.Net 7.3.4 or later. This change removes the unlisted dependency from future releases.

Validation

• Built src/Microsoft.ML.GenAI.Mistral/Microsoft.ML.GenAI.Mistral.csproj with its dependencies: 0 warnings and 0 errors.
• Confirmed that restore resolves JsonSchema.Net.Generation 5.0.4 and JsonSchema.Net 7.3.4.
• Used an isolated console runner with published Microsoft.ML.GenAI.Mistral 0.24.0-preview.26457.2 and Generation 5.0.4 on macOS ARM64 with .NET 10.0.11. Confirmed that the loaded Generation assembly reports version 5.0.4. Both existing prompt scenarios, with and without tools, match their repository approval baselines. The prompt-builder source is unchanged from the published release.
• git diff --check passed.

These are targeted build and runtime checks, not a full GenAI test-suite run.

JsonSchema.Net.Generation 5.0.2 is more than a year old. I guess we don't want to make big updates to dependency versions right now, but would it be worth updating to at least 5.0.4?
