ContentReviewLog doesn't need to attempt to retry HTTP requests as it reattempts them afterwards anyways, but if the HTTP requests are constantly failing it needs a way to notify users about it so proper action can be taken, either via a separate webhook or the same one (in the latter case error logging should be reduced to a single message with no important details about the error).

For the awaiting and rejected statuses, Wikia generates diff links with the live revision as the diff's base (i.e. oldid). This behaviour is particularly helpful when reviewing changes that span multiple revisions, and should be replicated.

For approved statuses, information about the previous live revision is lost, so a useful diff link cannot be constructed (without maintaining state). Wikia's behaviour is to generate a permalink (oldid without diff). To avoid confusion, this behaviour should also be replicated.

Discord trims the amount of embeds to around 20, so if over 20 scripts are approved at once only the first 20 (alphabetically) will appear.
