fix projectMembers.delete not including type

[mikewuu]

Fixes ('type' must be one of [workplace_user,group,invite,service_account].) error on projectMembers.delete

Issue

Was previously looking for {type_} with underscore, where the URL endpoint has {type}.

Notable things

• Also updated methods projectMembers.get & projectMembers.update

@Piccirello this is blocking seam.co from doing stuff, would appreciate a look!

FYI @nmanoogian. The Readme API docs look right but guessing it's something on that side.

Thanks for the ping, @Piccirello! And thanks @seveibar for reporting -- we'll take a look!

Hi @mikewuu (cc @seveibar) - I appreciate the effort you put into this PR, but unfortunately we can't accept it as the SDK is autogenerated from an OpenAPI spec and the changes would be clobbered the next time it runs.

We've created an internal issue to address this but I don't have an ETA for you at the moment.

@apazzolini no worries. I've created a public issue, #17, to track this as we're blocked here.
