Cardano GraphQL 8.2.1

What's Changed

• docs: disclaimer for chainfollower variables added by @Kammerlo in #883
• chore: upgraded db-sync by @Kammerlo in #885

Important Changes

• A new docker service, token-metadata-registry has been added to the docker compose file. This improves the syncing times of the off-chain asset data and overcomes the previous issues with the public Token metadata registry has a limit of daily requests. This brings in following changes when running GraphQL:

Important Upgrade notes

1. Run the new token-metadata-registry service present in the docker compose
2. Make sure the METADATA_SERVER_URI to point to local token metadata registry server
3. The Chainfollower environment variables CHAIN_FOLLOWER_START_SLOT and CHAIN_FOLLOWER_START_ID are currently mandatory. Otherwise the Token registry will get stuck. We will provide a fix as soon as possible.

Known issues

• Token syncing will get stuck, if the environment variables aren't set
