Rename of type alias defined with PEP 695 fails

[erictraut]

PEP 695 (introduced in Python 3.12) introduces a new type statement to define type aliases. If you use the language server "rename" feature to attempt to rename the type alias, it fails with an error message:

To repro:

1. Install the latest Python 3.12 rc1. Alternatively, set the pylance/pyright "pythonVersion" to "3.12".
2. Create a new file with the following contents.

type TA1 = int

x: TA1 = 1

3. Position the mouse cursor over either instance of TA1 and run the "Rename Symbol" command.
