Suggestion: Marked NSFW modmail threads should be marked as NSFW on the logs

[OviiiOne]

Is your feature request related to a problem? Please describe.
Not really. I like to review what the support team has answered when I was not active, and sometimes when I open the ticket logs I see things I cannot unsee now.

Describe the solution you'd like
If a modmail thread is marked as NSFW while it's open, the log sent to the log channel should indicate there's NSFW on that thread log.

Who will this benefit
I guess everyone who has access to the logs can benefit as they will know if there's something not safe in the ticket before opening it.
