Add map thumbnails for Vet Center CAPs to the Locations page

Status = BLOCKED

Blocked by either:

Adding CAP data to LH Facilities API - #9727
The current way facility map thumbnails are pulled in relies on querying the Facilities API. Since CAPs are not yet part of the Facilities API, this method will not work for CAPs

OR

Making Drupal CMS the source of truth for map thumbnails - #15672
There's already geolocation data in Drupal, so we could update the FE templates to rely on Drupal via Content Build / Next Build and remove the dependency on Vets Website / LightHouse Facilities API

Description

A Vet Center Locations page displays listings for the Main Vet Center along with, if affiliated, Outstations, Mobile Vet Centers, and CAPs.

Map thumbnails are displayed for the Main Vet Center and for Outstations but not for CAPs.
Example: On the Fargo Vet Center Locations page

• there are thumbnails for the Main Vet Center and Grand Forks Vet Center Outstation
• there is no thumbnail for the Fargo Vet Center - Bagley, MN

CAPs have a visible thumbnail in the Drupal interface (only visible to Content Admins) but it is not rendered on the front end. The page briefly appears to try and load but ultimately, the map is not displayed.

Steps to reproduce

1. Log into Drupal as a Content Admin
2. View the Fargo Vet Center - Bagley, MN CAP node in edit mode
3. Scroll down page and observe the map is visible in the Geolocation block
4. Visit the [Fargo Vet Center Locations page](https://www.va.gov/fargo-vet-center/locations/
5. Observe no map is displayed for Fargo Vet Center - Bagley, MN
   Note: map thumbnails are not expected for Mobile Vet Centers!

Acceptance criteria

• Map thumbnails for Vet Center Community Access Points are displayed on the relevant locations page below the images.
• Appropriate spacing and padding is applied.
• Map thumbnails are accessible to users of assistive tech
• Interactions with CAP thumbnails have the same interactive behavior as other location thumbnails

@xiongjaneg I think this might be a regression - I thought we previously displayed these

Will consider this in context of Vet Center 2.0

Pretty sure this is blocked by #9727 or #4411. Map images are called from dynamically from Facilities API via Vets Website (rather than statically generated from Drupal data via Content Build). Vet Center CAPs were not in previous iteration of the API. If they were added to Lighthouse v1 (and therefore available in Vets API v2), then this would be an enhancement.
