[Bug]: Python version inconsistencies

[fiv21]

What happened?

Within your examples you suggest python 3.9 or better will work, however, is not possible to install this repo SDK in python older than 3.13.

Can we make the sdk retro compatible to, at least 3.10 or better?

@rajeshvelicheti If this is valid for contribution, Shall I check with this?

From my understanding, Python 3.13 must be used with the A2A Python SDK because of required features in asyncio. I'll update the example.
