[Bug]: --index-json flag not honored when running against a local storybook

[ronakj]

Describe the bug

This is what the readme mentions

If you are running tests against a local Storybook but for some reason want to run in "index.json mode", you can pass the --index-json flag:

yarn test-storybook --index-json

However the code looks something like this (permalink)

const shouldRunIndexJson = runnerOptions.indexJson !== false && !isLocalStorybookIp;

Which will resolve to false even if the flag is passed. This seems like a bug.

The correct code should be

const shouldRunIndexJson = runnerOptions.indexJson === true || (runnerOptions.indexJson !== false && !isLocalStorybookIp);

To Reproduce

You can easily test this using any locally available pre-built storybook. Start a local server using http-server and try to run tests using --index-json flag. It will not be honored and storybook will try to read the storybook configuration which is not needed in index-json mode.

System

NA. Happening in every system.

I have a fix #539, but feel free to close if this is intentional. I unblocked my org with a patch for an older version of the package (as we are using storybook 7) so I am not in any hurry for this.
