v4.0.5

Welcome to v4.0.5 release of Prysm! This release contains many important improvements and bug fixes since v4.0.4, including significant improvements to attestation aggregation. See @potuz's notes here. This release is strongly recommended for all users.

Note: The released docker images are using the portable version of the blst cryptography library. The Prysm team will release docker images with the non-portable blst library as the default image. In the meantime, you can compile docker images with blst non-portable locally with the --define=blst_modern=true bazel flag, use the "-modern-" assets attached to releases, or set environment varaible USE_PRYSM_MODERN=true when using prysm.sh.
