Implement regular pickup RestAPI

Closes #1373 (closed) regular pickup API implementation

What does this MR do?

Adds an OpenAPI for regular pickup configuration for a store.

This allows configuring the regular picks for a store via RESTapi.

How confident are you it won't break things if deployed?

Not expected, it is an additional way to configure the regular pickups and should replace the very old Xhr way.

How to test

1. Checkout branch locally
2. Login as foodsaver
3. Save PHP_SESSION token for postman
4. Open postman
5. Run a PUT method on "http://localhost:18090/api/stores/5/regularPickup" with [{ "weekday": 1, "startTimeOfPickup": "12:01", "maxCountOfSlots": 5 }, { "weekday": 1, "startTimeOfPickup": "12:00", "maxCountOfSlots": 5 }]
6. Run a 'GET' method to ready the change back -->
