release: fill the 0.0.39 offline release fallback digests

[gitcommit90]

The offline release fallback is served when GitHub's release API is unreachable, and install.sh verifies the digest it returns. Those digests are the digests of the 0.0.39 release commit's own artifacts, so they could not exist in that commit — this is the follow-up that fills them in, after which the site is redeployed.

Until now the placeholder was deliberately not 64 hex characters, so latestLinuxRelease() rejected it and /api/releases/linux/latest answered 503 — failing closed rather than handing an installer a digest that could not match what it downloads.

Verified locally against what the build lanes reported:

Artifact	SHA-256	Bytes
1Helm-0.0.39-arm64.dmg	de381468…fd0b	504,397,451
1Helm-0.0.39-mac-arm64.zip	a35ba43a…4547	301,207,402
1Helm-0.0.39-linux-node.tgz	ac54f11c…b077	401,004,908

npm run ci: 122 tests, 120 pass, 0 fail.
