Cargo build warning: resolver

When running Cargo build, get warning before build completes:

warning: virtual workspace defaulting to `resolver = "1"` despite one or more workspace members being on edition 2021 which implies `resolver = "2"`
note: to keep the current resolver, specify `workspace.resolver = "1"` in the workspace root's manifest
note: to use the edition 2021 resolver, specify `workspace.resolver = "2"` in the workspace root's manifest

Fix: update root Cargo.toml with resolver of 2

[workspace]
members = ["crates/*"]
resolver = "2"

Version for rand doesn't update?

No idea why this happened.
