Add title to the block link

Moving to needs review as there is patch.

Hi @aluzzardi. I do agree that having more accessible attributes would be a good idea. That said, I don't know if just adding the block label would be enough as it is not really descriptive. The core Layout Builder block picker itself is not providing a title attribute.

I recently introduced 2 change which would allow developers to alter the generated markup and add the title if they need it with the wording they need:

• Block links are now rendered using a theme function ✨ Browser block item displayed via a theme function Fixed which allow developers to create their own template file to override
• A new hook_layout_builder_browser_alter() have been introduced ✨ Ability to Set Categories to Expanded/Collapsed Fixed to allow developer to alter the render array generated

Based on these feedbacks, I will close the ticket but feel free to reopen if you disagree or have a better option.
