# About the pull request

doctors spawn with dark blue scrubs, surgeons spawn with green scrubs

# Explain why it's good for the game
highly flavorful (soulful, even) and true to old scrub color hierarchies
where surgical scrubs are the green ones and medical scrubs are
/whatever/ color (dark blue usually for physicians, though). not
impeding in a meaningful way, i'd wager, since people can still freely
vend their preferred scrubs, just neat.

feels like this makes sense and fits since our nurses adhere to the
Scrub Hierarchy with their respective light blue scrubs on spawn

# Testing Photographs and Procedure

![image](https://github.com/cmss13-devs/cmss13/assets/29965103/4b614d87-93c9-4a05-af6f-e465a3db20d3)

one of them did residency for 3 years and one of them did residency for
five years !! you will now know!!! unless they go to their vendor, then
all bets are off !!

tested; without duplicating Every Thing from the parent doc datum for
the surgeon clothing datum, they spawn shoeless and bagless, and this
makes me sad. if there's a better way to NOT copy 5 extra lines, i'm all
ears

# Changelog

:cl:
add: Doctors will spawn in dark blue scrubs by default; Setting your
preferred job title to "Surgeon" for doctor roles will now spawn you in
green scrubs
