v4.0.0

Removed

• Context Extension is now disabled by default, and can be enabled with ENABLE_CONTEXT_EXTENSION
• Removed configurability of the Root / Landing Page Catalog stac_version via the
  STAC_VERSION environment variable. This is now fixed at 1.1.0.
• Child link relations removed from root (landing page).

Changed

• Use Node 22 by default.

Added

• To all endpoints that depend on collections, add support for a query parameter (GET)
  or body field (POST) _collections that will filter to only those collections, but
  will not reveal that in link contents. This is controlled by the "ENABLE_COLLECTIONS_AUTHX"
