Ghostty displays slightly incorrect palette colors

The colors that Ghostty actually displays are slightly shifted from palette codes defined in config.

For ex:
In config file:
palette = 04=#3840b2

Ghostty actually displays:
#3740b2
(according to my Mac color picker utility Sip)

This might be related to an existing issue which says:

...we don't do proper gamma correction from our linear RGB values that are used everywhere else (bg, fg, palette, SGR styles, etc.).
...
The result is that all specified color is a little bit off compared to native GUI toolkits

Issue: Gamma Correction #2125
