What is in this Pull Request ?

Fix Get-PnPTeamsChannel returning MembershipType with "unknownFutureValue" for shared channels instead of "shared".

As described in the Graph documentation at https://learn.microsoft.com/en-us/graph/api/resources/channel?view=graph-rest-1.0#properties , membershipType enum requires an additional header Prefer: include-unknown-enum-members to get the value of shared for shared channels, otherwise it will return unknownFutureValue .
