Fix rerun icon on action view component (#25531)

Right now rerun icon on action view component will not be seen when
duration text length is long, because the wrapper `job-brief-info` has a
fixed width, and the svg is squeezed. The way to fix this in this PR is
to change width to `fit-content` and exchange position of duration text
and rerun svg.

Before (rerun svg not shown on hover):
