Sam/875 project batch metadata

[S4mmyb]

Description

Finalized credit batch and project metadata for the VCS credit class. The only major changes was moving the 'additional certifications' from the project metadata to the credit batch metadata to align with Verra's representation of credit batches as well as removing monitoring and verification reports from the credit batch data to allow for easier automation in the future.

The current batch metadata structure only supports a 1:1 metadata mapping for credits bridged directly from the Verra, but not other bridges such as toucan which supports different data(toucan vintage metadata here). While this might have been more difficult to address at a certain point in time, our new strategy to allow for dynamic minting of batches allows us to circumvent the need for an exact metadata mapping for credit batches by introducing a BatchOriginTx parameter which allows us to determine the credits source bridge. This means that in the future, we will likely have two sets of metadata in the future to support batches coming over from toucan and batches coming directly from verra.
