[Events] See More Events link is not working correctly on events page

Problem/Motivation

The "See more events" button in the Upcoming Drupal Camps section on the /community/events page returns all types of events. It should just return upcoming Drupal Camps. Not trainings, etc.

Steps to reproduce

Go to https://www.drupal.org/community/events →
Select the "See more events" button in the Upcoming Drupal Camps section.

Proposed resolution

Fix the view to only return upcoming Drupal Camps (Event type = DrupalCamp)

Remaining tasks

User interface changes

Change button to read "See more Drupal Camps"

API changes

Data model changes
