Provide the possibility of adding requestOptions on any method performing a HTTP request

[bidoubiwa]

Currently, as per #1461 it is now possible to provide a custom httpClient and requestOptions when instanciating your Client.

See example:

meilisearch-js/tests/client.test.ts

Lines 52 to 66 in 870f0f5

	test(`${permission} key: Create client with custom headers (object)`, async () => {
	const key = await getKey(permission)
	const client = new MeiliSearch({
	...config,
	apiKey: key,
	requestConfig: {
	headers: {
	Expect: '200-OK',
	},
	},
	})
	expect(client.httpRequest.headers['Expect']).toBe('200-OK')
	const health = await client.isHealthy()
	expect(health).toBe(true)
	})

Ideally, we would like to be able to provide the requestOptions on any method that ultimately performs an HTTP call.
