CI: Allow warning emitted by scripts/static-analysis

What does this MR do and why?

When scripts/static-analysis sees a warning it prints it on stderr along with the following banner:

**** bin/rake config_lint had the following warning(s):

Since we are filtering certain warnings via fail_on_warnings we need to filter this line as well.

Refs https://gitlab.com/gitlab-org/gitlab/-/jobs/3525067604.

Fixes #386693 (closed).
