Change the icons in Careers list to match those in the info card

[Marina Alsahawneh]

Is your feature request related to a problem? Please describe.
We have recently updated the icons used in the careers' InfoCard component. Thus, it would be better if we updated the icons in the Careers' list as well.

Describe the solution you'd like

• The clock icon should be replaced with calendar-day.
• The map-marker-alt should be replaced with globe-europe.
