fix: repair external links in conformance spotlight

[immanuwell]

Two links in the published conformance spotlight are relative URLs.
Clicking them opens nested kubernetes.dev paths and returns 404. Small thing, but legit user-facing

Reproduce

curl -L -o /dev/null -w "%{http_code}\n" https://www.kubernetes.dev/blog/2023/10/05/sig-architecture-conformance-spotlight-2023/ii.nz
curl -L -o /dev/null -w "%{http_code}\n" https://www.kubernetes.dev/blog/2023/10/05/sig-architecture-conformance-spotlight-2023/apisnoop.cncf.io.

Both return 404

Fix

Use the intended HTTPS URLs for ii-Team and APISnoop. Both targets return 200 now, after the fix

Validation

The pinned Hugo v0.144.2 build rendered 882 pages, and the generated article contains absolute hrefs
