feat : use navigation plugin

[hirasso]

Description

Sooo. This PR escalated quite a bit 😅

• Pages can now be excluded from the rendering process and only live in the menus by setting permalink: false and eleventyNavigation.url: https://example.com/ in the front matter
• Introduced canonical link tags
• Added a heading "In this section" for pages with children
• Updated the sitemap to handle the new behavior
• Changed the external link icon 🫢

Fantastic :) Can we get the navigation plugin to open external links in a new tab? Currently, they seem to open in the same tab.

Not out of the box. I'll look into it.

The mobile menu button seems broken, or is that just me?

External links now opening in a new tab. Everywhere, not only in the menu 💅

Still works for me. But this would be the next optimization target, anyways I'd say :)

Guys, this is so much fun. 11ty rocks!!!

I guess I rushed a bit with adding the target="_blank" to all external links. I think I got a bit greedy with all the nice things eleventy offers 😅

I reverted everything external-link-related and re-implemented it as a progressive enhancement:

• don't add target=_blank to external links if on a touch device (I don't like tabs on mobile)
• Only handle links in the main navigation and "In this Section" lists.

I can't keep up with any of this 🤠 But it looks good to me!
