Subject: [PATCH] docs(devicetree): use the ev_ retained Evidence id prefix in
 the example

The retained-reference example wrote the Evidence id as "ev:<digest>".
Retained ids are "ev_" followed by the digest (prefixedDigestSchema in
src/domain/digests.ts), and inspect_analysis_view rejects the colon form
with invalid_format. Use the same "ev_<digest>" placeholder as the other
guides.

Fixes #7612
Supersedes #7760
