Remove isolatedConfig option
The isolatedConfig option is no longer supported by the @nx/webpack:webpack executor. Previously, setting isolatedConfig: false allowed you to use the executor's built-in Webpack configuration.
If this option is set in project.json, then it will be removed in favor of an explicit webpackConfig file. The Webpack configuration file matches the previous built-in configuration of the @nx/webpack:webpack executor.
