Schema doesn't offer the bundle type

[bepri]

Bug Description

The JSON schema for charmcraft.yaml files accepts defining a bundle charm, but it won't indicate to you that it's an option. It only suggests the "charm" type.

To Reproduce

Run charmcraft init. Then, replace the type key's value with something that doesn't exist, like msi, and check the validator error from your IDE.

Environment

Any
