[Bug] SDK doesn't support "New Copilot Studio" experience, but it's not indicated anywhere in the repo

Language/Version
What package version of the SDK are you using.

• Language: Python
• Package version: 1.2.0
• SDK Use: Clients

Describe the bug
The Learn doc for the SDK includes a small note indicating the Copilot Studio client library only supports "classic experience" agents, but the repo itself indicates this nowhere. We lost a day of development tracking this down, I'm hoping the main README or the Samples README can be updated with a similar warning before others encounter the same fate.

To Reproduce

1. Scan this repo for any warnings indicating "new experience" agents are NOT supported by the SDK.
2. Find no such documentation.

Expected behavior
Users should be able to learn which versions of Copilot Studio are supported by the SDK without having to leave the repo to read a Learn article.

thanks for calling this out.

This condition is temporary, as the MCS folks release the new experience without connecting the API endpoints up just yet.
Per our last discussion with the team responsible, they should be releasing a set of backend updates in the next few days ( or a week ) that will result in the SDK client working without any overt work on your behalf.

Both the new experience and the old experience use the same API.
