Enhancement: Extend `aad o365group add` with options to set `resourceBehaviorOptions`

resourceBehaviorOptions can be set only at creation time of an Microsoft 365 Group however currently we do not provide the ability to set them, therefore only the default behaviours are set. We should provide the ability to set these options to our own preference if they are provided.

Options

Option	Description
--allowMembersToPost [allowMembersToPost]	Set if only group members should be able to post conversations to the group
--hideGroupInOutlook [hideGroupInOutlook]	Set to hide the group in Outlook experiences
--subscribeNewGroupMembers [subscribeNewGroupMembers]	Set to subscribe all new group members to receive group conversation emails when new messages are posted in the group
--welcomeEmailDisabled [welcomeEmailDisabled]	Set to not send welcome emails to new group members

Resources

resourceBehaviorOptions is a string collection that specifies group behaviors for a Microsoft 365 group. These behaviors can be set only on group creation (POST).

Correct @nanddeepn. We keep isPrivate as-is for now.

@nanddeepn I’ve updated the spec based on the feedback from @waldekmastykarz slight adjustment in that the options should be flags rather than accepting a boolean value and adjusted the option description slightly.
