First check

• I added a descriptive title to this issue.
• I used the GitHub search to find a similar request and didn't find it.
• I searched the Prefect documentation for this feature.

Prefect Version

3.x

Describe the current behavior

Due to missing overload, pyright reports

async with get_client(sync_client=False) as client:
    ...

as error, since get_client returns Union["PrefectClient", "SyncPrefectClient"].

Describe the proposed behavior

Add typing overloads for client to get rid of error at least with the explicit argument sync_client

Example Use

Thanks for the issue @hikariatama! This was fixed in #13763 and the fix is available in 3.0.0rc3. I'm going to close this, but feel free to reply if you encounter any other issues with get_client typing!
