feat(sidekick): Generate more samples for oneof main setters. (#2592)

This now generates samples for the main setters of a oneof where the
`ExampleField` (i.e. variant) is byte, bool, like float or enum.

This currently will have no effect on Rust generated code because Secret
Manager and Workflows do not have oneof to which these changes apply.
