do-static-analysis.install-system-deps.sh errors on Debian 13 container

As part of #6 we discovered that running this script on debian:13 results in the following error:

stat: cannot statx '/var/cache/apt/archives': No such file or directory
Error: Unable to query the APT archive cache directory modification time.

It appears that the /var/cache/apt/archives directory isn't packed into the image(or stripped):

root@e0e21f229d97:/project# ls /var/cache/
apt/      debconf/  ldconfig/ 
root@e0e21f229d97:/project# ls /var/cache/apt/  

, hence the error.

We should consider the cache needs updating in this case instead.
