[BUG] (regression) 3.17.4 not loading config (color) on no-custom-classname

[Squixx]

Describe the bug
On 3.17.3 my config is loading correctly and all my linting succeeds, on 3.17.4 all files fail on colors which are supposed to be loaded from the config file.

To Reproduce
Have a project using custom colors, update to 3.17.4, run the linting rules with "tailwindcss/no-custom-classname": "error" {"config": "<path>"}

Seems to only ignore custom configs in the theme.extend. works for me if i move the colors object to theme instead of theme.extend.

Can anyone else confirm this?
