In some cases, we hadn't correctly wired in the `minimumReleaseAge`
checks for `digest`, due to the `currentValue` not changing.
To handle this, we need to:
- use our helper methods for calculating whether the `minimumReleaseAge`
has passed
- handle a new digest's new `releaseTimestamp`
the current timestamp
- intentionally not gate `minimumConfidence`, as this is only computed
per-release, not at the digest level
- note the fixed behaviour, and clarify when it will/will not work
- add coverage for all generated updates for `digest`s, including when
remapping a Go Modules update as a `digest`
- clarify that `filterInternalChecks` and
`applyMinimumReleaseAgeToDigestUpdate` should stay in sync
