Provide cargo init --workspace

[BartMassey]

Problem

Right now, it is very slightly inconvenient to set up a new Rust project with a workspace rather than as a standalone lib or bin.

Proposed Solution

In addition to cargo init --bin and cargo init --lib, it would be great to have cargo init --workspace, which just sets up Cargo.toml as a workspace with no members. Not a big deal, but perhaps also really easy?

Notes

No response

I think this might be a duplicate of #8365 if we keep parity between init and new.

Agreed. Apologies for the issue spam: I did do a search, honest, but somehow managed to miss the relevant issues.
