📝 docs(council): Add versioning and date of approval to AI Policy
    
    This commit edits the frontmatter of the Fedora AI-Assisted
    Contributions Policy to clearly note the document version (v1.0, the
    original and first version) and the date of the publication, which was
    when the git commit was merged into this repository on Friday, October
    24th, 2025.
    
    No changes to policy content; this just makes it easier for ourselves
    and the rest of the world to understand the versioning and cadence of
    our own policy documents. It also subtly encourages us to maintain a
    changelog, so we can always clearly explain what changes we made and
    why. Transparency++
