Add GitHub Pages index listing org repositories with links and Contribute section

[Copilot]

The repo had no web presence — just a README. This adds a single index.html at the repo root to serve as the GitHub Pages landing page for the OpenOptimizationOrg organization.

Changes

• index.html: Static page listing all public org repos (OPL, OFL, Overview) with name, description, and topic tags; styled with inline CSS using GitHub's design tokens (no external dependencies)
  • Each OPL and OFL repo card includes buttons linking to both the GitHub repository and the GitHub Pages website
  • A Contribute section at the bottom of the page provides:
    • Links to the Issues page for both OPL and OFL
    • A link to the Google Form for submitting new optimization problems (OPL only)

Enabling GitHub Pages

Settings → Pages → source: Deploy from a branch → main / / (root) → Save.

Original prompt

Make a basic github-pages page with a single file where we collect links to the public repositories in this organization

Make sure to have for both OPL and OFL the link to the github-pages website as well as the github repository. Also add a 'contribute' section, where for both a link is placed to the relevant issues page, and for OPL a link to the google form (https://docs.google.com/forms/d/e/1FAIpQLSehQp24AuFAH2j9jizDhq8K_BYgNGMKXWTMu6s-2RwEJrK59Q/viewform?usp=sharing&ouid=107462254722022409950) is included as well

Done in commit 991663e. Each repo card for OPL and OFL now has buttons linking to both the GitHub repository and the GitHub Pages site. Below the repo cards a new Contribute section has been added with a two-column grid:

• OPL: links to Issues & Feature Requests and the Google Form for submitting new problems
• OFL: link to Issues & Feature Requests
