container.clearInstances() should not clear ValueProviders

Describe the bug

One can register dependencies as ValueProvider via:

container.register(TOKEN, {useValue: myImpl});

Unfortunately container.clearInstances() unregisters dependencies registered via ValueProvider, which makes it impossible to resolve TOKEN after calling container.clearInstances().

To Reproduce

import "reflect-metadata"
import { container } from "tsyringe";

const DEP_TOKEN = Symbol("DEP");

const myDepImpl = {
  doStuff() {
    console.log("foo");
  },
} as const;

container.register(DEP_TOKEN, { useValue: myDepImpl });

container.resolve<typeof myDepImpl>(DEP_TOKEN).doStuff(); // prints "foo"

container.clearInstances();

// errors with: Error: Attempted to resolve unregistered dependency token: "Symbol(DEP)"
container.resolve<typeof myDepImpl>(DEP_TOKEN).doStuff();

Expected behavior
I would expect container.clearInstances() to only clear instances that were created via a ClassProvider or FactoryProvider but not via ValueProvider as it makes it otherwise impossible / impractical to use .clearInstances() in conjunction with ValueProviders.
