The SWC docs should emphasize up front that the setting is Webpack only. It mentions below that it only applies if @storybook/addon-webpack5-compiler-swc is enabled, but I think it should say this at the top, and make it more explicit.

@shilman appreciate the suggestion and I'll be more than glad to make the adjustments to make the documentation more explicit about this setting. I'll coordinate with Valentin on it.
