[retrouser955]

This pull requests adds the ability to configure application command context which allows the creation of user-installable commands.

I have not tested this feature yet so the pull request will be a draft for now.

Hey, I just have a couple of questions. Would you add the context of the application command usage CommandInteraction or CommandInteractionData?

Right now, I have it set to the former and I was just checking if changes are needed.

i spent 5 months trying to sort everything alphabetically/in a sensible easy-to-understand order in a previous pr, please make sure it's the same here :)

How do you suggest I could make it more sensible? Also, are there any other properties that needs to be alphabetically sorted? I would like to tackle these in a single day rather than a back and forth.
