Fixes collective availability for teams with overlapping day timezones (#3898)

* WIP

* Fix for team availability with time offsets

* Prevent empty schedule from opening up everything

* When no utcOffset or timeZone's are given, default to 0 utcOffset (UTC)

* timeZone should not be part of getUserAvailability

* Prevents {days:[X],startTime:0,endTime:0} error entry

* Added getAggregateWorkingHours() (#3913)

* Added test for getAggregateWorkingHours

* Timezone isn't used here anymore

* fix: developer docs url (#3914)

* fix: developer docs url added

* chore : remove /

* chore : import url

* Test fixes

* Reinstate prisma (generate only) and few comments

* Test fixes

* Skipping getSchedule again

* Added await to expect() as it involves async logic causing the promise to timeout

* Test cleanup

* Update jest.config.ts
