fix: MSTeams not created as online meetings (#21377)

* fix MSTeams formatting and duplicate events

* update without changing scopes, create onlineMeetings through CalendarService instead of VideoApiAdapter

* get url after online meeting is created required for downstream

* fallback to callvideo if only MSteams and update evt.videoCallData with url

* for backward compatibility set explicitly 'Microsoft Teams Meeting' for old meetings if rescheduled

* add dependency to msTeams App

* nit

* use interpolation

* update to create MSTeams event if only MSTeams installed and not Outlook Calendar

* make function MSTeams specific
