Feat: Discord integration

[jcodog]

Option to let users send a notification to their Discord server when they post a new tweet through contentport.

Option to let users post announcements to their Discord servers about whatever they are working on in the same way they do for tweets.

• Previously discussed with both Josh and Jo. Looking for more interest to start working on this as a PR.

thanks for posting here, curious about this use case too 👀

• Would use webhooks over bots for better use case, and customisability for the users.
• Tweet posted notifications would include a link to the tweet like bots such as dyno and mee6 do using other methods to check if you have posted to socials
• Would have a 2000 character limit for announcements written by the ai and sent to an announcement channel.
