Site header: informix-db → informix-driver

Match what users see when they `pip install informix-driver`. Also fix
two broken social links: PyPI was pointing at the now-404 informix-db
project, GitHub link was pointing at github.com/rsp2k/informix-db
(repo doesn't exist there — source lives on Gitea). Rewired to:

- Source (Gitea): git.supported.systems/warehack.ing/informix-db
- PyPI: pypi.org/project/informix-driver
- editLink: Gitea's _edit/branch/main URL pattern

Logo SVG aria-label + title also updated for accessibility consistency.
