Can't set agents when agent type is `false`

[shellvon]

Describe the bug

• Node.js version:
• OS & version:

Currently , the agent type is:

got/source/core/options.ts

Lines 44 to 48 in 23b2f26

	export type Agents = {
	http?: HttpAgent | false;
	https?: HttpsAgent | false;
	http2?: unknown | false;
	};

as you can see, false is a valid type, but when i set agent to false, it throws an error!

got/source/core/options.ts

Lines 1136 to 1146 in 23b2f26

	set agent(value: Agents) {
	assert.plainObject(value);
	// eslint-disable-next-line guard-for-in
	for (const key in value) {
	if (!(key in this._internals.agent)) {
	throw new TypeError(`Unexpected agent option: ${key}`);
	}
	// @ts-expect-error - No idea why `value[key]` doesn't work here.
	assert.any([is.object, is.undefined], value[key]);

Actual behavior

Can't set agent when agent type is false

Expected behavior

change type declare (maybe remove false type?) or just make false as a valid type when set agent, I think the latter would be better.

Code to reproduce

// just set agent to false.
