Demos UI updates (#21)

* Update package version and improve styling

- Updated `BlazorExpress.Bulma.Docx` package to version 0.2.2.
- Modified `HeroSubTitle` in `Index.razor` to remove specific dark text styling.
- Added new CSS variable for dark theme background in `blazorexpress.chartjs.demo.rcl.css`.

* Update component link from "Form Components" to "Utils"

Removed the "Form Components" link and added a new link titled "Utils" under the same category "@DemoPageLinkCategory.Utils".
