chore: [#1303] remove explicit declaration of workspace members from Cargo.toml

For packages included in the main Cargo.toml file.

The application works anyway because _all [path dependencies](https://doc.rust-lang.org/cargo/reference/specifying-dependencies.html#specifying-path-dependencies) residing in the workspace directory automatically become members_.

See https://doc.rust-lang.org/cargo/reference/workspaces.html#the-members-and-exclude-fields.

We have to keep `console/tracker-client` becuase it's not included
directly in the main Cargo.toml as a dependency.
