Add favicon for Google Search results (#7205)

- A side-quest from "7166 improve search metadata".
- The favicon must be from the same domain as the homepage, so the CDN URL couldn't be used, hence the additional upload.
- The favicon also needs to be multiples of 48x48 and above.
    - Wanted to use SVG for the smallest size possible, but seems like Safari does not fully support it. Got Dejan to give me a reasonably-sized PNG.
