Cut a release with the updated digest crate

[Stebalien]

digest was updated to 0.10 but there's no corresponding bls12_381 release. Any chance we could get one?

[emlowe]

yes, please release a new crate.

[flightofthefox]

yes, please release a new crate.

This is going to be combined with the upcoming ff and group releases due to the rand 0.9 crate release impacting basically the entire of RustCrypto (including digest).
