Clarify: does `cache-all-crates` also cache workspace crates?

[brotskydotcom]

In the docs, the mention of CI tooling seems indicate that cache-all-crates is meant to apply only to dependent crates including dev dependencies, whereas cache-workspace-crates applies only to workspace crates and not dev dependencies.

Could you please clarify this in the docs? Or perhaps, if cache-all-crates does include workspace crates, could you add a cache-dev-dependencies flag that means only that? Thanks!
