Issues in the info.yml of module.

I was just checking the codebase of the module and saw some spelling mistakes and poor descriptions. Here is what I think we should change in Info.yml file.

Name: "Appointment Time Slots"
Description: "Appointment time slots module provides you with a field type, that allows you to select and set time slots for a particular date."

We should also remove the "package" key from the info.yml file.
