Fix the macOS download link 404ing

publicDownloadUrl built the disk image URL from manifest.version, but the version carries a build suffix the release tag does not: version "1.0.0-alpha.3.app.59" lives under tag "1.0.0-alpha.3". Every macOS visitor was handed a 404. Derive it from the updater URL instead, rewriting only the filename so the tag comes from the release directory the manifest points at.

Chris Tsang	1adde15f42	Fix the macOS download link 404ing publicDownloadUrl built the disk image URL from manifest.version, but the version carries a build suffix the release tag does not: version "1.0.0-alpha.3.app.59" lives under tag "1.0.0-alpha.3". Every macOS visitor was handed a 404. Derive it from the updater URL instead, rewriting only the filename so the tag comes from the release directory the manifest points at.	2026-08-27 00:00:13 +01:00
