[cards][Feature Request] Add line numbers and copy to clipboard functionality to codeblocks in Adaptive Cards

[LordBoBCUP]

Currently CodeBlocks do not render correctly in teams or devtoolsplugin. Codeblocks dont have line numbers, and are in adaptive card that isn't even copyable. We would like to see a copy to clipboard button and correct line numbering working on the CodeBlock adaptive cards in teams (at least on web/desktop where the documentation already states they are supported).

Currently we see the codeblock rendered in what looks like some kind of container that is then not even selectable to copy manually let alone provide line numbering and other features of the codeblock. highlighting does seem to work correctly.

I have tried both 2.0.0-preview.2 and 2.0.0-preview.3 as well as different versions on the adaptive card itself from 1.2 to 1.6 with no change.

Here is the basic code sent as a test in my app.on('message'...

const AC = new AdaptiveCard();
        AC.version = '1.5';
        AC.id = '12345';
        AC.body = [
            new CodeBlock({
                codeSnippet: `/**\n* @author John Smith <john.smith@example.com>\n*/\npackage l2f.gameserver.model;\n\npublic abstract strictfp class L2Char extends L2Object {\n  public static final Short ERROR = 0x0001;\n\n  public void moveTo(int x, int y, int z) {\n    _ai = null;\n    log(\"Shouldn't be called\");\n    if (1 > 5) { // what!?\n      return;\n    }\n  }\n}`,
                language: 'Java',
                startLineNumber: 61,

            })
        ];
        await send(AC);

It looks like on the various repos there have been many requests for this functionality in order to improve app's UX in teams so it would be good if this could be given some priority.

Hi @LordBoBCUP, thanks for the feedback. DevTools is now using embedded Adaptive Cards, so what is displayed is exactly what is seen on Teams, as you have pointed out. This request needs to be sent to the Adaptive Cards team. I have messaged my team with your feedback, and I'll get back to you when we determine the best way to route these types of requests to the correct team. Assigning to myself for now as a spike.
