chore: add missing transitive dependencies

Add dependencies that were only available transitively through other
packages but were being imported directly:

- csstype and copy-to-clipboard in @backstage/core-components
- @storybook/react-vite in @backstage/ui
- react-aria-components in @backstage/plugin-notifications
- @octokit/core in @backstage/plugin-scaffolder-backend-module-github
- @rjsf/utils in example-app-legacy
