fix(consensus): update Zebra's hard-coded blockchain checkpoint lists

[teor2345]

Motivation

Updating the checkpoints should speed up the full sync tests.

Solution

This updates the checkpoint lists as at 2022-02-22:

• mainnet: to the latest finalized tip
• testnet: to the latest Canopy checkpoint, because we expect a NU5 testnet rollback (Rollback NU5 testnet 1, and set consensus parameters for testnet 2 #3018)

This is part of #2368, but I didn't check off any tasks, because we'll need to update the lists again closer to NU5.

Reviewer Checklist
