v.1.26.3 breaks storybook config

[csantos1113]

The problem

storybook config from .percy.js is fully ignored even though it should be possible based on the docs: https://github.com/percy/percy-storybook/tree/master#percy-config-file-options

Environment

• Node version: v20.9.0 but it doesn't matter
• @percy/cli version: v1.26.3 where the issue starts; but it happens in all newer versions too
• @percy/storybook version: v4.3.6 or v4.3.7 - fails in both

Details

it does work in v1.26.2

I'm using yarn as my package manager; and it ended up being an issue with internal percy dependencies not upgrading correctly.
