Updates GitHub Actions workflows to use ubuntu-22.04 runners with Python 3.5.10 installed via pyenv, since actions/setup-python no longer supports Python 3.5.x on ubuntu-22.04.

Changes

Both workflows (.github/workflows/build-test.yml and .github/workflows/github-pages.yml):

• Runner: ubuntu-20.04 → ubuntu-22.04
• Python setup: Replaced actions/setup-python@v6 with:
  • Build dependencies installation using awalsh128/cache-apt-pkgs-action@latest for caching (libssl-dev, zlib1g-dev, etc.)
  • pyenv installation via pyenv.run
  • Python 3.5.10 compilation and global activation
• Cache: Added actions/cache@v4 for $HOME/.pyenv/versions (key: ${{ runner.os }}-pyenv-3.5.10)

github-pages.yml deploy job:

• Runner: ubuntu-20.04 → ubuntu-22.04

Both pyenv Python cache and apt packages cache significantly reduce build times on subsequent runs.

This pull request was created as a result of the following prompt from Copilot chat.

Update two GitHub Actions workflow files to run on ubuntu-22.04, install Python 3.5.10 using pyenv, and cache the pyenv-built Python at $HOME/.pyenv/versions.
