This PR adds admin equivalents of the `read:custom_emojis` OAuth scope: `admin:read:custom_emojis` and `admin:write:custom_emojis`. This is so tools which only touch emojis can run without other admin permissions. (`slurp emojis import` is one such tool.) I've also sorted the admin section of the scopes lists alphabetically like the non-admin section, and updated the Swagger test script to print the same command path that it actually runs. ## API compatibility Neither [Mastodon](https://docs.joinmastodon.org/api/oauth-scopes/) nor Akkoma nor Iceshrimp.NET has an equivalent scope, so there are no alternate scope names to worry about.
