[AdaptiveCards.Templating] Package Downgrade Error due to Newtonsoft.Json via AdaptiveExpressions

The simplest possible project referencing this library fails to compile:

<Project Sdk="Microsoft.NET.Sdk">
	<PropertyGroup>
		<OutputType>Exe</OutputType>
		<TargetFramework>net6.0</TargetFramework>
	</PropertyGroup>

	<ItemGroup>
		<PackageReference Include="AdaptiveCards.Templating" Version="1.3.1" />
	</ItemGroup>
</Project>

The error:

Error NU1605 Detected package downgrade: Newtonsoft.Json from 12.0.3 to 11.0.2. Reference the package directly from the project to select a different version.
AdaptiveCardTemplateRepro -> AdaptiveCards.Templating 1.3.1 -> AdaptiveExpressions 4.11.2 -> Newtonsoft.Json (>= 12.0.3)
AdaptiveCardTemplateRepro -> AdaptiveCards.Templating 1.3.1 -> Newtonsoft.Json (>= 11.0.2)

Tested using Visual Studio 2022 17.4.0.

Workaround

Add reference to Newtonsoft.Json:

<Project Sdk="Microsoft.NET.Sdk">
	<PropertyGroup>
		<OutputType>Exe</OutputType>
		<TargetFramework>net6.0</TargetFramework>
	</PropertyGroup>

	<ItemGroup>
		<PackageReference Include="AdaptiveCards.Templating" Version="1.3.1" />
		<PackageReference Include="Newtonsoft.Json" Version="12.0.3" />
	</ItemGroup>
</Project>

Start by inspecting the package dependency metadata for AdaptiveCards.Templating 1.3.1 and its AdaptiveExpressions 4.11.2 dependency. Reproduce the NU1605 error with the minimal net6.0 project, then verify that a corrected dependency declaration restores the project without requiring a direct Newtonsoft.Json workaround.
