Translatable default file name for screenshots

[Cobinja]

This makes the word "Screenshot" in the default file name for screenshots translatable.

This causes errors like

Unpacking cinnamon-common (6.7.2+alfa) over (6.7.2+alfa)…
Setting up cinnamon-common (6.7.2+alfa)…

Have you installed a different system python? This should be tolerated in 3.12+. I can't reproduce it.

No. It's just the Ubuntu python:

$ dpkg -l | egrep '^ii  python3 '
ii  python3                                    3.14.3-0ubuntu2                              amd64        interactive high-level object-oriented language (default python3 version)

Thanks. I have edited the script by hand, and sudo dpkg-reconfigure cinnamon-common does not show errors any more.
