CI: fix CIS test failures caused by truncated ps output

[petrutlucian94]

The CIS tests are currently failing if we remove some Python
dependency constraints.

The reason is that these tests run a few "ps" commands and receive
truncated output[1].

As a workaround, we'll explicitly set the terminal size using
the COLUMNS env variable.

Nice find! Do you have a dry-run in Jenkins to link?

I didn't try the Jenkins job, it was occurring in GH actions.
