[Fix][CI] Improve release notes for published packages and images

[SuperMarioYL]

Purpose

Improve GitHub Release notes with published image repositories and version-pinned Python package installation instructions.

This PR only changes Release-note rendering, its tests, and documentation. Squash merge into feature/cicd is appropriate. It does not synchronize develop or resolve the feature/cicd -> develop conflict; upstream maintainers should resolve that conflict in the subsequent PR.

Modifications

• Display published Docker Hub links alongside GHCR links.
• Generate version-pinned PyPI/TestPyPI installation instructions from completed publication receipts.
• Keep unpublished Python-index channels out of the installation section.
• Update the Release documentation and focused regression tests.

Test

• Local release tests: 562 passed, 4 skipped.
• Ruff, Black, isort, and actionlint with the repository CI configuration passed.
• git diff --check passed.
• Fork Push Commit Checks for 5d3a1be7: C++ build/unit tests, C++ formatting, and Python checks all passed.
