Update graph-ts and graph-cli

[Bruno Menezes]

📄 Context

We use @graphprotocol/graph-cli and @graphprotocol/graph-ts. The CLI for reading the manifest, compiling the mappings to AssemblyScript and other actions and the graph-ts provides APIs to access the graph node store, data on IPFS, etc. We need to upgrade the libraries to their latest version, currently graph-ts@0.31.0 and graph-cli@0.51.2

• Create the corresponding issue if an update requires major work.
• Make sure dependencies are updated in the lock file (yarn.lock).
• Verify whether everything is working as expected. i.e. Running the tests and indexing a subgraph using the new versions.
