Make the "Interaction Failed" error more informative for users using User Apps while missing External Apps Permission

[TwilightZebby]

...specifically when said User App is responding to a Button/Select using the UPDATE_MESSAGE Interaction Response, for a publicly viewable Message sent by another User who does have USE_EXTERNAL_APPS Permission using that User App's Slash Command.

It would be more helpful to have the red error shown under the button/select say something along the lines of "Missing Use External Apps Permission to use this Button" in this situation :)

For those wanting to re-create this:

1. Have two accounts on a Server; Account A with Use External Apps Permission and has the User App installed - and Account B not having either of those.
2. Have Account A use the User App's Slash Command to send a public message with a Button/Select into the Server's text chat.
3. Have Account B press/use the Button/Select on said message, and the User App should attempt to respond to that Interaction using an UPDATE_MESSAGE Response type to edit the message.
4. Observe the result

What I expected was to at least see a "Missing Use External Apps Permission" style error under the Button/Select for Account B.

Instead, a generic "Interaction failed" error shows, which isn't helpful to anyone as it doesn't give any hint as to why said Update Message Interaction response doesn't actually work.
The end user is left wondering if the User App's developer is at fault for making a faulty User App, and said developer is left wondering why their code doesn't work in very specific servers but does work in others & in DMs/GroupDMs.
