v3.0.0

We are happy to announce Prysm v3.0.0. This is our merge release. All mainnet users MUST upgrade to this release before the Bellatrix fork by Sept 6, 2022, 11:34:47am UTC. Users who fail to upgrade will fork off from the canonical chain. We recommend upgrading to v3.0.0 at the earliest convenience. Asides from upgrades, users will need to make changes to the knowledge that's similar to previous testnets. We recommend the following preparation for the merge doc: https://docs.prylabs.network/docs/prepare-for-merge
