Fix the documentation on Stripe Connect

Both TidyCal FAQ and [Booking Types]https://help.tidycal.com/article/686-booking-type) and Connect your Payment Services
mention a legacy third payment option called TidyCal. The problem is both pages explain TidyCal, requires Stripe Connect. But the regular Stripe option requires Stripe Connect as well, so it's very confusing.

Meanwhile, How do I charge for my appointments? (Connecting Stripe or PayPal) doesn't mention Stripe requires Stripe Connect.

It may sound trivial to you but Stripe Connect is super limited in its supported country list, so it's crucial to know when it's used.

In the first group of pages, please explain both the modern and legacy option require Stripe Connection.

In the last page, please mention Stripe Connect in the first place.
