Design a branding package for the docs and landing page

[ETA444]

I have designed a comprehensive branding package with Adobe Illustrator, consisting of:

1. Main logos: Used across the docs and website.

   • Big logo (dark mode)
   • Big logo (light mode)
   • Small logo

2. Social cards: Various social cards which appear when specific links are shared (e.g. explore_df module, docs landing, website landing, etc.)

   • Main social card for website and banner on GitHub
   • Main social card for docs landing page
   • Main social card for GitHub when repository is shared
   • Social card for Explorer modules
   • Social card for Transformer modules
   • Social card for Evaluator modules
   • Social card for Predictor modules

3. Favicon: Used as the favicon for the docs and website.
