Fix Read the Docs build for ubuntu-24.04

[Copilot]

• Update .readthedocs.yaml build OS from ubuntu-20.04 to ubuntu-24.04
• Add cmake and doxygen to apt_packages for ubuntu-24.04
• Replace deprecated pkg_resources with importlib.metadata in docs/conf.py
• Fix isort import ordering in docs/conf.py (stdlib before third-party)

Original prompt

Please update the Ubuntu version used on read the docs to at least 24.04 or lts-latest

[dfm]

@copilot it looks like that's failing on read the docs with a different error. Please fix!

Added cmake and doxygen to apt_packages in .readthedocs.yaml (commit 8c23c0a). These are needed on ubuntu-24.04 for scikit-build-core C++ compilation and Doxygen API doc generation respectively — they were likely pre-installed in the ubuntu-20.04 RTD image but aren't in 24.04.

Warning

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:

• docs.readthedocs.io
  • Triggering command: /home/REDACTED/work/_temp/ghcca-node/node/bin/node /home/REDACTED/work/_temp/ghcca-node/node/bin/node --enable-source-maps /home/REDACTED/work/_temp/copilot-developer-action-main/dist/index.js (dns block)
• readthedocs.org
  • Triggering command: /home/REDACTED/work/_temp/ghcca-node/node/bin/node /home/REDACTED/work/_temp/ghcca-node/node/bin/node --enable-source-maps /home/REDACTED/work/_temp/copilot-developer-action-main/dist/index.js (dns block)

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)

@copilot i think the problem is that pkg_resources isn't installed

Replaced pkg_resources with importlib.metadata (stdlib since Python 3.8) in docs/conf.py in commit 3a64a0f.

@copilot please fix the pre-commit errors in conf.py

Fixed in 8028a85 — moved the importlib.metadata stdlib import before the third-party sphinx_material import to satisfy isort.
