Ingest Processors missing optional fields

[seanstory]

🐛 Wrong type

Ingest Processors, pretty much all in this list:
https://github.com/elastic/elasticsearch-specification/blob/main/specification/ingest/_types/Processors.ts

Many are missing optional fields. The most important of which are description and tag, which likely should be part of the ProcessorBase, unless there really are any processors that do not support these. But I think they all do.

Definition

If possible provide a snippet with the fix.

 export class AttachmentProcessor extends ProcessorBase {
  field: Field
  ignore_missing?: boolean
  indexed_chars?: long
  indexed_chars_field?: Field
  properties?: string[]
  target_field?: Field
  resource_name?: string
+  remove_binary?: boolean
+ description?: string
+ tag?: string[]
}

Chatted with Sean and I believe our type annotation for tag is correct as string instead of string[]. However description and other properties are missing from some processors.
