The autoReplaceStringTemplate was outputting {{{newDigest}}} which
resolves to just the hex hash (e.g. 04e2738...) without the sha256:
prefix. Since the regex expects to match "sha256:(?<currentDigest>)"
and the file stores digests as "sha256:HASH", the replacement produced
a digest value missing the prefix. Renovate detected this mismatch
("Digest is not updated") and failed with "Error updating branch:
update failure".
