Use short array syntax

I found several dozen additional instances that need to be converted to short array syntax. The PHP Code sniffer report is attached - additional code standard violations are listed but you can focus on the Short array syntax must be used to define arrays ones.

Also want to make sure you're aware of this if you aren't already https://www.drupal.org/docs/8/modules/code-review-module/installing-code.... Once you have this installed, you can generate reports such as the one attached, and quickly identify areas that need code standards fixes.

A local code sniffer would catch these errors so you can confirm a patch works before uploading it here. Drupal Slack can be a good place to get assistance if you're having trouble getting the steps in the Code sniffer guide to work.

You'll eventually want to get testing set up on your local environment as well. The initial setup is a bit of work and probably not necessary for this specific task, but will make contributing to future issues much easier.

Thanks. Found one more and fixed that too.

I fear you did that by hand. You might want to know that there are scripts for that, see how core did it: #2776975: March 3, 2017: Convert core to array syntax coding standards for Drupal 8.3.x RC phase
