fix(html-reporter): duplicate attachment name (#16929)

Fixes #16456.

The extra span/name was coming from
077b8a9289/packages/html-reporter/src/links.tsx (L72)
(in conjunction with the line above it).

These two lines assume `path` and `body` are mutally exclusive.

Regression likely introduced by the PR that added the now removed line #10778.
