[barnett617]

This PR implements the archives menu with a SITE config to control whether to show it.

The new page "archives" groups the posts by its publish year then month and demonstrate all the posts archived like below

And it shows well on mobile devices

Sorry ifs not the right place to say this. I like this feature, but I see all the posts was showing, even the not published (draft true). Its ok, but the real problem is the draft posts are not created, cause are draft, not published.
So, they are listed, cover and link, but result in a 404 page.
I know is just make a filter, but I have technical debts to make this work.

@patrick-kot
I see your concern, but draft posts can be filtered out during dev and prod modes.
I checked this out in my local and fixed that draft issue. Anyway, thanks for pointing this out.

Love this PR. @barnett617
However, I noticed that the current layout has some issues.
If the site has a relatively long name, it breaks the layout.
This problem also persists in the existing AstroPaper implementation, though the shorter menu length helps minimize its impact.

To fix this, we could add a little icon menu like the ones we have for Search and Theme. That would make things look more minimal.

Another approach is to add an Archives link at the bottom. Something like this

It looks good to me, this is also a feature related to the theme layout.
Just feel free to adjust it follows your favor and design.

So, here's what I did.

• filtered draft posts
• updated menu layout
• updated/archives to redirect to 404 page if SITE.showArchives is set to false
• updated the docs
• rebased from main to resolve conflicts

I'm gonna merge this now.
Again, thanks for your contributions.
