Job running time always titled as “Elapsed time”

Summary

Following !75811 (merged), the running time of a job in the job sidebar now always shows Elapsed time and never Duration.

Steps to reproduce

1. Trigger a pipeline
2. Open a job
3. See that the running time of the job is labelled as Elapsed time
4. Wait for the job to complete (fail or pass)
5. See that the running time is still labelled as Elapsed time

Example Project

Job: https://gitlab.com/KevSlashNull/gitlab/-/jobs/1875922875

What is the current bug behavior?

The running time of a job is labelled as Elapsed time, regardless whether the job is running or not.

What is the expected correct behavior?

The running time of a job is labelled according to the following table:

Job is running	Job has finished
Elapsed time	Duration

Possible fixes

I tested this locally and it looks like the job doesn’t have the finished_at field value. That means that the label is always Elapsed time in app/assets/javascripts/jobs/components/sidebar_job_details_container.vue.
