fix: use available Python 3.10.20 in docs CI workflow

[Copilot]

CI was failing because actions/setup-python was requesting Python 3.10.18, which is no longer available on GitHub-hosted runners (only 3.10.20 is available).

Change

• .github/workflows/docs.yml: bump python-version from 3.10.18 → 3.10.20

Original prompt

The CI job fails because it requests Python version 3.10.18 (x64), which is unavailable. Only 3.10.20 (x64) is available. Update the workflow file (.github/workflows/docs.yml) to set 'python-version: 3.10.20' instead of 3.10.18 in all relevant steps using actions/setup-python. This should fix the workflow failure.

The following is the prior conversation context from the user's chat exploration (may be truncated):

User: Please find a solution for failing job 67287579334. Use the logs, job definition, and any referenced files where the failure occurred. Keep your response focused on the solution and include code suggestions when appropriate.

Assistant: The job failed because Python version 3.10.18 (x64) was not found. The available version is 3.10.20 (x64).

Solution:
Update your workflow file (.github/workflows/docs.yml) to use python-version: 3.10.20 instead of 3.10.18. For example:

- uses: actions/setup-python@v4
  with:
    python-version: '3.10.20'

This change will resolve the failure.
