Add setting to enable log timestamps

[AlanGreene]

Changes

Depends on #2146
Closes #2145

Add a toggle to the Settings page to allow users to display timestamps
on the step container logs. This produces a timestamp prefix on each
line in the same way as kubectl logs <pod> --timestamps and uses
the functionality provided by the Kubernetes API server.

we still don't see timestamps on the logs even when enabled on the dashboard 🤔
Can someone share a working screenshot?

This was introduced in Dashboard v0.19.0 and is working as expected in recent releases.

Here's an example with it disabled:

Enable it in the settings:
