chore: update default catalog to dcp55 and add release notes

[Copilot]

Updates the default catalog version and adds release notes for two new projects.

Changes

• Catalog version: Updated from dcp54 to dcp55 in site-config/data-portal/dev/config.ts
• Release notes: Added November 21, 2025 entry in docs/dcp-updates.mdx with two new projects:
  • A Single-Nucleus Atlas of Human Prenatal Inner Ear Development
  • The normal human lymph node cell classification and landscape defined by high-dimensional spatial proteomic

The changes follow the established pattern from previous catalog updates (e.g., #2854).

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
