[issue44399] log rotator cookbook example might waste disk space

In https://docs.python.org/3/howto/logging-cookbook.html#using-a-rotator-and-namer-to-customize-log-rotation-processing, the log rotator example deletes the original log file after compressing it. However, running on Linux the command "lsof +L1" shows that the deleted original log file might still hold the same disk space, and keep growing.
Replacing the command "os.remove(source)" with "os.truncate(source,0)" seems to solve the issue by freeing the original log file disk space at each rotation.
