Add config option to disable Blog link in top navbar

[rambleraptor]

Describe the pull request

This creates a new config option that allows you to stop the "Blog" link from appearing in the navbar.

Why

With the existance of starlight-sidebar-topics, the blog can be accessed through the sidebar. In my website, I'd like to stick with the normal navbar and not use the new theme selector.

How
Added config option and plumbed through.

Thanks for the contribution 🙌

I am currently exploring various possibilities to customize how and where the blog link is actually displayed, as users have requested different options for this. I am not sure yet how this will be implemented/configurable so I don't think I want to add a new option for this yet that I'll probably have to deprecate later.

There are also some important changes coming to Starlight that will highly change how this plugin is structured, e.g. the entire Sidebar override will probably be removed soon and also potentially make both plugins easier to use at the same time as it's not that easy right now.

I guess one possible workaround for now could be to add a custom override for the ThemeSelect component in your Astro configuration, and just render the default Starlight one which would remove the blog link.

I'm definitely taking note that on top of multiple options, some users might want to have no link at all and have full control over it 👍

Any ideas on when the Sidebar override will be removed? I'm really keen to try and get starlight-sidebar-topics implemented with the blog plugin.

As withastro/starlight#2390 is required, I would suggest subscribing to it as once merged and released, it would be a good indicator that the refactor can be started.
