Edit link in breadcrumb region shows even when user has no permission

#4 Works for me! Thanks.

Unfortunately, the approach with PathValidator::isValid doesn't really achieve what's needed. The permission check only looks for the permission link to any page, but that doesn't necessarily mean that the current user is allowed to edit the current entity. The rest of the patch looks ok, but the permission check needs a different approach.

I have started an MR which uses the simple entity access controller to see if the user has edit permissions.

#11: the merge was blocked by a conflict and I (unsuccessfully) tried to rebase from upstream, sorry about the mess

#14: this is the new branch with the cherry picked commit by @jurgenhaas, with the merge fix.
I had to change the fix given that I tried with different roles and one of them (implementer) wasn't able to see the breadcrumb despite having the permission "[CT]: Edit its own content".

See here the differences between a moderator and a implementer:

The issue was basically the same as this one https://www.drupal.org/project/drupal/issues/3204423 → , caused by the confusion of the names between "edit" and "update" for the entity access check.
Before: $entity->access('edit')
After: $entity->access('update')

Now it works nicely has expected, please review.

Thanks @elgandoz for updating the MR. Unfortunately, it only applies to 1.0.x-dev but not to 1.0.0-RC3 because of this commit: https://git.drupalcode.org/project/gin_toolbar/-/commit/4e66cd7c20b249be...

But there isn't much we can do about that.

Hey @jurgenhaas, I removed the commits past your one and amended it, in order to have the 'update' access check, in the original 3319445-edit-link-in branch you created, and force-pushed.
So now the diff from MR!25 should apply on 1.0.0-RC3, while MR!30 goes on 1.0.x-dev in order to get merged.
Please check since I didn't test it.

Thanks @elgandoz that's a nice solution as well. So MR !25 is for the latest RC3 and MR !30 is for the dev release. This is working great.

Rebased

MR!30 didn't apply any longer and I've done a rebase. However, one part of the fix needs to be handled in Gin now, since the part of the template where this is required has moved over there.

The rebased one was missing some twig changes, I happened to worked on fixing this before having found this issue :facepalm:

I a very similar thing and went ahead and push it, it makes it cleaner in the the twig and uses the proper drupal services.
