Move to official Storybook 7 release

[jattasNI]

Pull Request

🤨 Rationale

Right after I submitted the upgrade to a release candidate of Storybook 7 in #1134, I noticed they released the official 7.0.0. Adopting the latest patch addresses some of the issues in #1146.

👩‍💻 Implementation

1. Update to latest non-RC build in package.json and regenerate package-lock.json
2. Regenerate one patch file since the file it was patching has a new name
3. Add another patch file since they introduced another instance of [Bug]: 7.0.0-rc.8 Cannot find module 'lib/types/dist' in @storybook/html storybookjs/storybook#21820
4. Move off deprecated API for specifying sourceTransform as described in migration guide
5. Delete storybook-declarations.ts since this bug was closed [Bug]: 7.0.0 - Module '"@storybook/addon-actions/decorator"' has no exported member 'withActions' storybookjs/storybook#21887

🧪 Testing
