Describe the bug

Teams channel does not show citation list correctly when I call TurnContext.sendActivity with some citations as the following:

\"citation\":[{\"@type\":\"Claim\",\"position\":\"2\",\"appearance\":{\"@type\":\"DigitalDocument\",\"name\":\"Contoso Electronics Company Overview\",\"abstract\":\"Contoso Electronics Company Overview\\n\\nDisclaimer: This document contains information generated using a language model (Azure OpenAI).

It is highly a Teams server side bug because I found that all activities were correct set before sent to request as part of request body. https://github.com/microsoft/botbuilder-js/blob/67a570875eec4ea00eaeb4b551249b6787a427db/libraries/botbuilder-core/src/cloudAdapterBase.ts#L87

For context: Citations are related to AI content such that appropriate markup can be provided in the Activity to highlight the source of data. This has not been added to BF SDK yet and is not expected to work yet. Everything so far is POC. Leaving this issue open as a marker for parties that may have seen demos and are curious. In the near future we will open offfical issues with details and PR's.
