Problem

When using cargo remove, specifying a dependency name that is not present in Cargo.toml results in an error message suggesting the "closest" package by name.

Currently, if foo is a dependency:

$ cargo remove fo
    Removing fo from dependencies
error: the dependency `fo` could not be found in `dependencies`; dependency `foo` exists

The "dependency foo exists" part is unclear, particularly if the crate name is longer and the typo in the command is not noticed right away.
It comes from

Proposed Solution

Option 1

Change the message to something such as "Did you mean...?"

$ cargo remove fo
    Removing fo from dependencies
error: the dependency `fo` could not be found in `dependencies`; Did you mean `foo`?

Option 2

Use closest_msg

$ cargo remove fo
    Removing fo from dependencies
error: the dependency `fo` could not be found in `dependencies`
help: a dependency with a similar name exists: foo

Notes

Option 2 is closer to the compiler's message if you typo a variable name.
