Remove unused import statement as it causes tkinter error

[Axedyson]

This PR fixes the following error:

Traceback (most recent call last):
  File "/home/anders/Project/Auto_Jobs_Applier_AIHawk/main.py", line 27, in <module>
    from ai_hawk.job_manager import AIHawkJobManager
  File "/home/anders/Project/Auto_Jobs_Applier_AIHawk/src/ai_hawk/job_manager.py", line 8, in <module>
    from turtle import color
  File "/usr/lib/python3.12/turtle.py", line 101, in <module>
    import tkinter as TK
ModuleNotFoundError: No module named 'tkinter'

by removing the import statement from turtle import color from the file, which can be done as the import statement is not being used.

I'm on WSL2 by the way.
