Pin message without sending system message

[MinnDevelopment]

I made a simple bot which adds 2 message context commands:

The motivation for this is to allow users to pin messages without the permission to manage messages. This is because the manage messages permission allows to also delete messages.

I can't make this bot http-only, because it has to delete the user pinned message in this channel system message each time it pins a message. To do this, I have to listen for a message create event using a gateway connection.

My request is similar to #1617, as I want to be able to pin messages without this system message appearing. My bot sends its own message, because it also can tell you who pinned the message through the bot.

I hope that with the motivation for http-only bots, this feature request will not be rejected again. The previous reasoning does no longer apply.
