Adding a [registries] Entry

Example registries entry - would be written to $CARGO_HOME/config.toml or other configuration path:

index = ""

One this has been set, cargo will recognize the registry in various subcommands via the --registry flag, e.g.:

cargo publish \
--registry my-crate-registry

When a registries entry has not been set, Cargo will return a "no index set" error:

$ cargo update
error: failed to parse manifest at `~/src/my-private-crate/Cargo.toml`

Caused by:
  no index found for registry: `my-shipyard-registry`
