Should not fire onDidSendMessage for requests

[roblourens]

The debug adapter fires onDidSendMessage for requests that should be sent to the kernel.

vscode-jupyter/src/client/debugger/jupyter/kernelDebugAdapter.ts

Line 327 in 231d6fd

this.sendMessage.fire(message);

This should only be fired for messages going to VS Code (events, responses, and requests handled by VS Code itself)

[roblourens]

Fixed in #7226

@roblourens what are some verification steps for this change?

[DavidKutu]

There's an error message from VS Code that should show up on the Jupyter Output if we fire that for requests.

set this setting to get the debug messages:
"jupyter.logging.level": "verbose"

Removing verification-needed label because it isa bug and it is included by default in verification list
