Missing `mixed` for paragraphSpacing / paragraphIndent / listSpacing

[gluck]

These properties can be mixed in a TextNode (they can be defined on a range), but typings is missing it:

interface NonResizableTextMixin currently is:

  paragraphIndent: number
  paragraphSpacing: number
  listSpacing: number

should be:

  paragraphIndent: number | PluginAPI['mixed']
  paragraphSpacing: number | PluginAPI['mixed']
  listSpacing: number | PluginAPI['mixed']

Thanks for the report! I've made a ticket internally so our team is aware of the issue
