Support `can_admins_bypass` on `CreateUpdateEnvironment`

[jvm986]

We implemented the can_admins_bypass field on the Environment struct here.

Ideally we can add this to the CreateUpdateEnvironment struct here as well.

As with the previous implementation, this feature is very new and not yet documented in the api documentation. However it is functional.

NB: I will create a PR within the next day or so.
