Dhruv Manilawala 78bbf6d403 New Singleton enum for PatternMatchSingleton node (#8063) ... ## Summary This PR adds a new `Singleton` enum for the `PatternMatchSingleton` node. Earlier the node was using the `Constant` enum but the value for this pattern can only be either `None`, `True` or `False`. With the coming PR to remove the `Constant`, this node required a new type to fill in. This also has the benefit of narrowing the type down to only the possible values for the node as evident by the removal of `unreachable`. ## Test Plan Update the AST snapshots and run `cargo test`.		2023-10-30 05:48:53 +00:00
