Fix Chromatic build failure by updating build-storybook script (#5276)

* [release] Increment version to 1.26.8

* [fix] Fix Chromatic build failure by updating build-storybook script

Replace nx build-storybook with direct storybook build command to properly
forward --output-dir argument from Chromatic deployment.

Fixes invalid Storybook build issue where static files were empty due to
Nx not passing through command-line arguments to the underlying Storybook
build command.
