bixal-site-drupal - bug: Cache tags not properly set for new accreditations

[mattsqd]

Describe the bug
The accreditations are added to the footer at https://github.com/Bixal/bixal-site-drupal/pull/304/files#diff-403405aee515577c358da9d49904bc3564354594cae76b6d62540e8f711787d2R48 and https://github.com/Bixal/bixal-site-drupal/pull/304/files#diff-403405aee515577c358da9d49904bc3564354594cae76b6d62540e8f711787d2R46. However these are rendered, they need to depend on the cache tag that is used to get the data. Ie, the object that is updated when https://www.bixal.com/admin/content/accreditations is saved.

Because this does not happen, when the accreditations are saved, they Drupal cache is not cleared so the changes will not be shown.

To Reproduce

1. Go to the homepage as an anonymous user
2. Open an new browser or incognito and login as admin
3. Go to /admin/content/accreditations
4. Make a change to the accreditations
5. Go back to the homepage as an anonymous user

Expected behavior
Changes made are shown after the update.

Please note that this is most likely a bug in config_pages as I used their API to grab the data, unless I got it wrong. Check the issue queue first. Check for a better API to retrieve the fields or submit a patch to make proper cache dependencies.
