Update hook_help for Book module

The text for the hook_help looks good in my opinion, however the url() calls needed to be updated to the drupal-8 style. This patch does that.

one small thing, the tokens for routes should use ! rather than @

'@link' becomes '!link'

Patch changes '@link' to '!link'

This sentence seems like it could use a touch of reengineering from a word smith.
You can assign separate permissions for creating, editing, and deleting book content, as well as adding content to books, and creating new books.

Other than that everything seems to be in order and receives a passing grade.

Changed sentence from #4 to

You can assign separate permissions for creating new books as well as creating, editing, and deleting book content.

Excellent, the permissions section reads much easier and all the technical bits are working as intended. Good Work everyone!

This looks wrong <em>creating new books</em> as well as<em>creating</em> no space between as and creating.

Just manually reviewed the patch and it is good to go as far as this issue is concerned. I did find an issue #2112237: Regression: Remove EntityFormControllerNG from book module, but this does not block this task since the page exists, it is only sick for the time being.

Probably makes sense for Jennifer to give this a sign-off.

Sorry, I apparently missed this one!

In About, the reference to the online docs is not following our current template.

Other than that, this looks good!

Fixed the online docs link

Patch applies, links are okay and text is conform the guidelines

Thanks for the new patch and quick review! Agree this is ready to commit.

Thanks all! Committed to 8.x.
