Allow bot tokens to upload RPC assets

[Mstrodl]

I would like to be able to upload RPC assets using an application's bot token, similar to how dispatch used to work.

Some background: I maintain elcord, a rich presence client for emacs. Elcord displays an icon for the current major mode for the buffer you have focused. There are lots of major modes, so many people submit PRs to add icons for their favorite major modes. This is fine, but it means I need to make sure the icons submitted are uploaded as RPC assets. This is tedious, so I wrote a script to upload the assets and a github action that gets triggered whenever I merge one of these PRs. Currently, that script uses a user token, but that's not ideal because it expires occasionally. I'd like to be able to use the token for the application's bot to upload assets for the application, similar to how dispatch allowed you to use a bot token to upload builds.

you don't need to upload rich presence assets in the dev portal anymore, you can just put any image URL in your code (in place of the asset key)

[devsnek]

using urls is the correct approach here. rpc assets are not intended to be modified regularly, or in any automated fashion.

[Mstrodl]

@devsnek The only changes I make are adding a new asset every 2-3 months. Is that too regularly?

[devsnek]

it is not, but it is automated. it looks to me like you could likely use https://github.com/Mstrodl/elcord/raw/master/icons/{name}.png as a url.

I believe conventional wisdom is that github don't like being used for that, though the only place I can think to find a source for that off-hand is the old rawgit faq:

GitHub does this because serving raw files from a git repo is inefficient and they want to discourage people from using their GitHub repos for static file hosting.

External hosting really isn't the answer to this problem. You have a provided CDN and yet you're discouraging the use of it? Relying on both Discord's barely-working-as-is media proxy let alone said external host to be working 100% of the time is just annoying.
