fix(react-combobox): Stories should import from react-components

[behowell]

Previous Behavior

Combobox/Dropdown stories import directly from react-combobox. This causes the lint rule @fluentui/no-restricted-imports to fail in unrelated PRs, such as #27492. (I'm not sure why the lint rule isn't failing in the main build...)

New Behavior

Change Combobox/Dropdown stories to import from react-components instead of react-combobox.
