Storybook: Cleanup potentially unnecessary action spies

[tyxla]

In order to get the Storybook v8 upgrade to pass in #67574, I added some action spies, because without them, I was getting these errors for a few stories:

See these for more details:

• The action spies I added: 7bfce92
• Migration docs: https://github.com/storybookjs/storybook/blob/next/MIGRATION.md#implicit-actions-can-not-be-used-during-rendering-for-example-in-the-play-function
• Discussion: Storybook: Upgrade to v8.0.x #67574 (comment)

We believe that this isn't an optimal solution, as this feels like a false positive.

So, we should remove those action spies, but to do that we need to learn what really tricks Storybook into causing those errors, and how we can work around it better.
