Subject: [PATCH] Serve topic logos from explore-feed.github.com instead of
 github.com
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The topics block was emitting logo URLs as
`https://github.com/github/explore/blob/main/...?raw=true`, which
github/github's CSP doesn't allow as an img-src on biztools pages
(e.g. https://admin.github.com/biztools/topics) — so the logos fail
to render.

The collections block above already uses `{{ site.url }}` (which is
https://explore-feed.github.com per CNAME), and that host is the
intended canonical home for these assets. Switch the topics block to
the same pattern. The companion CSP allowlist change in github/github
adds `explore-feed.github.com` to img-src.
