FIX: public_file_server.enabled is false in test (PR #8192)

After a small conversation, we decided that we can set public_file_server.enabled to false in the test environment to have the same value as production.


You’ve signed the CLA, lis2. Thank you! This pull request is ready for review.

I support this change, anything that brings test closer to prd without impacting perf makes me happy.
