fix(revert): Reverts storybook-addon-mock inclusion

[michael-s-molina]

SUMMARY

Many of our stories in Storybook are throwing errors. After intensive investigation and the help of git bisect, I was able track the inclusion of storybook-addon-mock dependency in #23429 as the root cause for the errors. I investigated for a couple of hours to understand the reason why it was generating the errors but I wasn't able to resolve the issue. During the investigation I found that there is an open issue with the addon that also need to be addressed. Given that this is affecting many stories, this PR reverts that dependency to give us time to further investigate the problem without blocking Storybook development.
