Since cargo commands create a lock using the smallest msrv in the workspace, it can prevent getting up-to-date dependencies

PR content/description
Cargo commands will create a lockfile using the smallest msrv in the workspace.
This leads to a situation where crate A with a high msrv will be restrained to dependencies compatible with a low msrv because of an unrelated crate B in the workspace.
To simplify this, we set a common msrv for the workspace.
I did not update the version of zk-pok and versionable because they are already updated by #2950
