Support binarySource=install for cargo

[rarkins]

What would you like Renovate to be able to do?

Allow dynamic switching of cargo version at runtime

If you have any ideas on how this should be implemented, please tell us here.

It seems like we don't dynamically install cargo today, so maybe there is nothing to be done:

renovate/lib/manager/cargo/artifacts.ts

Lines 17 to 29 in ec723e3

	let cmd = `cargo update --manifest-path ${quote(manifestPath)}`;
	// If we're updating a specific crate, `cargo-update` requires `--workspace`
	// for more information, see: https://github.com/renovatebot/renovate/issues/12332
	if (!isLockFileMaintenance) {
	cmd += ` --workspace`;
	}
	const execOptions: ExecOptions = {
	docker: {
	image: 'rust',
	},
	};
	await exec(cmd, execOptions);

If so then we should note this here for the record before closing.

Is this a feature you are interested in implementing yourself?

Maybe

Maybe allow installing rust dynamically? So it can also use for runtime install mode?

[rarkins]

Yes, but I was thinking to do all the managers first and then languages in second phase

ok, so cargo is included in rust so nothing to do here.
