Accessing Subgraph Metadata

**Is your feature request related to a problem? Please describe.**
I'd like an easy way to access in-depth metadata about a subgraph

**Describe the solution you'd like**
-

**Describe alternatives you've considered**
Manually grabbing metadata from brittle ipfs

**Additional context**
IPFS is brittle

**Implementation checklist**
- [ ] Task 1

The issue requests a way to access subgraph metadata, likely from IPFS, but does not specify what metadata or where to add it. Look at the existing subgraph and GraphQL interaction code in the repository to understand how metadata is currently fetched. Determine where to add a new method or endpoint for retrieving metadata, and check if there are existing tests for similar functionality.
