1 week ago I don't think we can do much about the favicon, unfortunately, as long as agda-unimath is hosted at https://unimath.github.io/agda-unimath/ — quoting Google documentation, we're restricted by:
Google Search only supports one favicon per site, where a site is defined by the hostname. For example, https://www.example.com/ and https://code.example.com/ are two different hostnames, and therefore can have two different favicons. However, https://www.example.com/sub-site is a subdirectory of a site, and you can only set one favicon for https://www.example.com/, which applies to the site and its subdirectories.
Since we're a subdirectory of unimath.github.io, our favicon is set by unimath.github.io; there is currently no favicon for that, and it would set one for both agda-unimath and UniMath.
The third point about "preview content" (usually called "description") is tricky. Best we could do is set a <meta> description tag, but search engines rarely respect those. See Google's documentation:
Snippets are primarily created from the page content itself. However, Google sometimes uses the meta description HTML element if it might give users a more accurate description of the page than content taken directly from the page.
Emphasis might*. I doubt Google can properly judge what is an accurate description of a literate Agda file. My experience is that the search engines will just put whatever they want in there — I checked search results on some websites with proper description tags, and DuckDuckGo, Google and Bing all show different snippets from the page; none of them show the description tag text.

The library still appears in this less-than-favorable form in Google's search results:
There's a few issues to point out that could be improved.
