workspaces::types::PublicKey doesn’t implement std::hash::Hash

[mooori]

This prevents storing it in a std::collections::HashSet, which can be helpful during testing.

workspaces::types::PublicKey is a wrapper around near_crypto::PublicKey, which implements Hash. So it should be possible for workspaces::types::PublicKey to derive Hash. Would a PR that adds Hashto the derived traits be welcome?

Oh thanks for bringing this up. Lots of types in workspaces are there more on a need basis, so some stuff might've been missed. There's a couple things missing from PublicKey that would be nice to have as well. I'll include this in that PR as well
