feat: stripeConfig server options and related types

[Sandro Circi]

Following the official stripe-node repo and its documentation it could be beneficial to add all the other available options:

---

From the original README, some of the configurations are:

Option	Default	Description
apiVersion	null	Stripe API version to be used. If not set, stripe-node will use the latest version at the time of release.
maxNetworkRetries	0	The amount of times a request should be retried.
httpAgent	null	Proxy agent to be used by the library.
timeout	80000	Maximum time each request can take in ms.
host	'api.stripe.com'	Host that requests are made to.
port	443	Port that requests are made to.
protocol	'https'	'https' or 'http'. http is never appropriate for sending requests to Stripe servers, and we strongly discourage http, even in local testing scenarios, as this can result in your credentials being transmitted over an insecure channel.
telemetry	true	Allow Stripe to send latency telemetry.

Note
Both maxNetworkRetries and timeout can be overridden on a per-request basis.

Ofcourse this introduces some breaking changes, since apiVersione should be configured under stripe.serverConfig.apiVersion instead of the old stripe.apiVersion.
