feat(docs): Improve display of index note navigation

- Updated the rendering of the `FoundIndexNote` component in `Docs.razor`
- Added logic to conditionally display index note navigation based on the presence of a non-empty `VaultPath`
- Modified the `VaultDisplayOptions` property initialization to include a trailing space for consistency
