Fix UnmetDependenciesException

Problem/Motivation

When an install profile lists this module to be installed, the following Exception occurs:

Drupal\Core\Config\UnmetDependenciesException: Configuration objects provided by <em class="placeholder">broken_link</em> have unmet dependencies: <em class="placeholder">views.view.broken_link (views)</em> in /app/web/core/lib/Drupal/Core/Config/UnmetDependenciesException.php:98

The issue is that the module contains a views configuration in config/install/, but does not list views as a dependency, nor allows this to be optional.

Steps to reproduce

For convenience, I have reproduced the issue here. But you may reproduce it with the following steps:

1. Create a basic install profile *.info.yml, listing the following:
   

   dependencies:
     - broken_link
   

2. Install the profile.

These steps should produce the error noted above.

Proposed resolution

Move views.view.broken_link.yml from config/install/ to config/optional/.

OR

List views as a dependency in broken_link.info.yml.
