security: move orval to dev dependency (#8569)

Looking at https://github.com/Unleash/unleash/security/dependabot/204 it
seems that the dependency comes from orval that should not be needed in
production:

```shell

```

These are dependencies that are optional for your project. If they fail
to install, the installation process will continue without error, but
they will be included if they can be successfully installed.

By default, optionalDependencies are installed in both environments,
including production.
