* remove empty file
If the endpoint is to be implemented later, the file can be added back,
but for now it is confusing to have an empty file.
* enhance(doc): document defaults
Default for `isPublic` is based on the database schema default value.
Defaults for `local` and `withFiles` are based on the behaviour of the endpoint.
* enhance(doc): explain nullable emoji category
* fix: make nullable if default is null
* enhance(doc): explain mute attribute expiresAt
* fix: define required fields
- `notes/create`: the default for `text` has been removed because ajv can not handle
`default` inside of `anyOf`, see
https://ajv.js.org/guide/modifying-data.html#assigning-defaults
and the default value cannot be `null` if text is `nullable: false` in the `anyOf`
first alternative.
- `notes/create`: The `mediaIds` property has been marked as deprecated because it
has the same behaviour as using `fileIds`, but the implementation tries to handlè
`fileIds` first.
- The result schema for `admin/emoji/list` has been altered because the `host`
property will always be `null` as it is filtered this way in the database query.
See packages/backend/src/server/api/endpoints/admin/emoji/list.ts line 67.
