Bump SSZ version for larger bitfield SmallVec (#6915)

NA


  Bumps the `ethereum_ssz` version, along with other crates that share the dep.

Primarily, this give us bitfields which can store 128 bytes on the stack before allocating, rather than 32 bytes (https://github.com/sigp/ethereum_ssz/pull/38). The validator count has increase massively since we set it at 32 bytes, so aggregation bitfields (et al) now require a heap allocation. This new value of 128 should get us to ~2m active validators.
