tide_os_color and tide_os_bg_color variables not properly set from __tide_detect_os

[adhdtiger]

Describe the bug

prompt os icon color does not propagate from that set in __tide_detect_os function.

Steps to reproduce

-Using tide configure function, set icons to "many" on a linux distro (debian in my case)

-The prompt os icon does not adopt the color indicated in the __tide_detect_os function.
-in fish_variables file, tide_os_color and tide_os_bg_color variables remain set to 'normal' instead of color hex code indicated in __tide_detect_os function (even after tide reload or reload of terminal)

tested with fisher install and manual install
