Add a PartialEq implementation to generated types

[blinsay]

Here's a quick attempt at adding PartialEq to gateway type implementations for #52. I tried adding Eq as well, but it looks like ObjectMeta and friends don't actually implement Eq.

error[E0277]: the trait bound `ObjectMeta: Eq` is not satisfied
   --> gateway-api/src/apis/standard/gatewayclasses.rs:16:5
    |
16  |     CustomResource, Serialize, Deserialize, Clone, Debug, JsonSchema, Default, PartialEq, Eq,
    |     ^^^^^^^^^^^^^^ the trait `Eq` is not implemented for `ObjectMeta`

To make these changes, I updated update.sh and the generate enums xtask to include auto-deriving PartialEq where I could and regenerated with a fresh install of kopium.

$ kopium --version
kopium 0.20.1

Thanks for adding this! Please note you'll just need to sign off on commits in the kube-rs org (more details here).

LGTM, let's start with this and maybe later we can dig in further on Eq for ObjectMeta. Thank you!
