Make book navigation block cacheable

This extension is being deprecated, see 🌱 [Meta] Tasks to deprecate Book module Active . It will be removed from core and moved to a contrib project, 📌 [11.x] [Meta] Tasks to remove Book Active .

This issue may be re-opened if it can be considered critical → , If unsure, re-open the issue and ask in a comment.

Wonder if anyone can confirm this is still needed since the last patch was for D8?

If still a valid task please reopen for 2.0.x of book contrib.

Yes, it is still relevant: https://github.com/drupal/core/blob/10.3.0-rc1/modules/book/src/Plugin/B...

Probably just needs a reroll

May need to re-look at the solution as it's breaking tests.

Ended up going with node_list and adding a book_settings tag for when the form is saved.
