docs: Remove threw(obj) from docs

[mroderick]

Since the introduction of threw in 0feec9ffba0da6bc2996cefa0c6e71872e8bedb2, no one have reported that threw(obj) doesn't work as the documentation states.

const sinon = require("sinon");
const o = { pie: "apple" };
const f = sinon.fake.throws(o);

f();
// this is supposed to return true
f.threw(o);
// => false

Since it has been 12+ years without an error report, it's safe to assume that no one uses the threw method in this way. Let's remove it from the documentation.

I'm not sure if this should have a version bump at all

Why not remove the threw prop at the same time and clean it up? Or fix it? Now it is just left as historic scraps

Using no argument spy.threw() or with a named error type spy.threw("TypeError"), threw works as documented.
