ci: Revert "add clang-tidy to Debian x86_64 base image"
Revert !7699 (merged). Our clang-tidy job runs under Fedora, and we need the plugin to compile there anyway, so lints like IWYU will best be done in the Fedora image.
Issue: #23912
A GitLab update will be applied on May 23, between 8am and 10am, EDT (UTC-04:00). This site may have intermittent delays during that time.
