refactor(ObjectPage): remove unless conditional (#8551)

To fix this, remove the redundant `headerArea &&` in the
`headerContentVisible` prop passed to `ObjectPageAnchorBar`, since the
entire block is already guarded by `headerArea && titleArea`.

Best single fix (no functionality change):
- In `packages/main/src/components/ObjectPage/index.tsx`, inside the
`ObjectPageAnchorBar` JSX props (around line 772), change:
  - `headerContentVisible={headerArea && headerCollapsed !== true}`
  - to
  - `headerContentVisible={headerCollapsed !== true}`

No new imports, methods, or dependencies are needed.
