Copy tab link array is missing localized_options key

Problem/Motivation

Apparently it a "localized_options" array is required in the "#link" sub array of a local task tab. If you don't have it, you can get an "TypeError: Unsupported operand types: array + null" error.

Though, this might be specific to some themes. I figured it out via: https://www.drupal.org/project/bootstrap_barrio/issues/3280356#comment-1... →

This is the full error:

The website encountered an unexpected error. Try again later.

TypeError: Unsupported operand types: array + null in bootstrap_barrio_preprocess_menu_local_task() (line 552 of themes/contrib/bootstrap_barrio/bootstrap_barrio.theme).

I actually ran into this a while back and thought it had been fixed here: https://www.drupal.org/project/entity_copy_reference/issues/3347826 🐛 all admin-structure menus(Content Types, Taxo, Menu, Views, etc) are inaccessible after activating entity_copy_reference module Needs review But I'm guessing the "localized_options" part of my patch didn't get merged.

Steps to reproduce

Visit a node that has the copy local task tab.

Proposed resolution

Add an empty array with the key "localized_options" to the copy tab menu array's "#link" array.

Remaining tasks

Implement the fix.

Attached is a patch file that works on my site. I haven't done any other testing. But it shows where the array needs to go.

Oh, and I think I originally was on Drupal 8 or 9 when I first ran into this. This time around I had to upgrade cweagans/composer-patches to the 2.x dev version before composer could apply the patch for me.
