🧪 Tests for deployment to dev passed ✅

Add verification tests of the output JSON.

Remove ApplicationInsights as it is not AoT-compatible (and I never look at the data anyway).

- Use System.Text.Json for serialization instead of Newtonsoft.Json to support AoT. - Remove unused/duplicate custom `JsonSerializerContext`. - Add more end-to-end tests.

Enable publishing the Lambda for AoT.

Harden `SkillRequestExtensions` against null properties on the request and make it easier to debug.

Add missing brace.

Increase code coverage for ending a session.

Sort the properties.

Save some lines.

Until there's a GitHub Actions Linux runner with arm64 support, need to switch back to x64 as it is not possible to compile AoT for arm64 on an x64 Linux image.

Include the ICU libraries for linux-x64.

Make the type non-abstract to see if it fixes `NotSupportedException` when attempting to deserialize the payload.

Remove polymorphism as it is not supported when the type discriminator is not the first property in the JSON document. See dotnet/runtime#72604.

Use invariant globalisation and remove Microsoft.ICU.ICU4C.Runtime to reduce the AoT deployment size.
