`glab ci list`: display `running` pipelines in blue
### Problem to solve
When running `ci list`, the output text is, by default, grey. Only `failed` and `success` gets colored in red and green.
What is very painfully missing is having color for `running` pipelines - they are important for quick scanning (for CI health, for identifying if my MR's latest pipeline is still in progress, and so on).
GitLab's web UI uses blue for `running`, which is common for "in progress" tasks in modern design languages.
### Proposal
Draft solution is in !3037 - it also increases test coverage for relevant method to cover "what happens if there are no pipelines", and very slightly refactors it.
### Further details
It's a simple change. I just joined the community and wanted to learn GitLab's community-forks flow on something fairly simple and hopefully uncontroversial ;)
