[NodeJS Templating] Expose adaptivecards-templating version

[anna-dingler]

Description

Expose the adaptivecards-templating library version by adding a variable $_acTemplateVersion to IEvaluationContext and TemplateObjectMemory. $_acTemplateVersion holds a JSON with versioning info.

Sample Card

{
    "type": "AdaptiveCard",
    "version": "1.0",
    "body": [
        {
            "$when": "${$_acTemplateVersion.major < 2}",
            "type": "TextBlock",
            "text": "Uhoh! Time to update your copy of `adaptivecards-templating`!"
        },
        {
            "$when": "${$_acTemplateVersion.major >= 2}",
            "type": "TextBlock",
            "text": "`adaptivecards-templating` is up to date!"
        }
    ]
}

Hi @anna-dingler. Thanks for helping make the AdaptiveCards JS renderer + tooling better. As additional verification, once the JS build succeeds, please go to the test site to test out your website/designer changes.

You may update the document late. I don't know how to track it before we release this change
