CI: specs_without_cluster jobs should not occur on docs branches
Summary
We do not need the specs_without_cluster and production_specs_without_cluster jobs to occur on documentation branches. This MR adds the relevant except:refs regex to correctly skip these jobs.
Steps to reproduce
Notice that this job was triggered for a branch beginning with docs- (undesirable).
Configuration used
Current behavior
specs_without_cluster and production_specs_without_cluster jobs are occurring on documentation branches.
Expected behavior
specs_without_cluster and production_specs_without_cluster jobs do not occur on documentation branches.
