[STORY 2-3] Update the ipfs metadata json schema and support milestone specific data (also applies to creation)

[wtfsayo]

• add image support for entire invoice
• Add metadata for each milestone
  • Title
  • estimated proposal
  • Add image

We will be relying on IPFS rather than updating the subgraph with this functionality as Nouns Builder is solely relying on IPFS metadata anyway.

[benedictvscriticus]

• one image supported in the metadata, and only one image is supported in the UI
  • further images both for proposal and milestone are handled as documents
  • could handle the specification for the frontend through mime types (optional)
• parsing of metadata should be improved
