[FEATURE]: Host time-tables available publicly in the app and allow teachers to put recurring zoom links there

[NikhilCodes]

Description

This feature can act as a reminder to students and allow the app to act as a single destination for both students and teachers to send the schedules for classes which is presently being done over a series of whatsapp groups instead.

Create a timetable section, with subject name bubbles. On click meeting link should pop up and let user choose if he/she would join the same.
