contrib/add_cosigner: fix for python 3.13
This script used to work, I assume my breakage is due to the python version.
```
Traceback (most recent call last):
File "/home/user/wspace/electrum/./contrib/add_cosigner", line 35, in <module>
version_spec = importlib.util.spec_from_file_location('version', 'electrum/version.py')
^^^^^^^^^^^^^^
AttributeError: module 'importlib' has no attribute 'util'
```
What changed, and why it matters
This is a trivial compatibility fix for a helper script. In Python 3.13, using importlib.util requires explicitly importing importlib.util. The change adds that missing import so the script can load a version file again. There is no security issue here.
No security action needed. Treat as a normal maintenance/compat fix.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The commit adds ‘import importlib.util’ to contrib/add_cosigner. In Python 3.13, importlib no longer exposes util as an attribute unless the submodule is imported explicitly, causing an AttributeError when calling importlib.util.spec_from_file_location(). The patch restores the script’s functionality on newer Python versions.
