[heft] update storybook plugin to be compatible with v9

[UberMouse]

Summary

1. updates the heft-storybook-plugin to be compatible with storybook v9, this only required adapting to the bin change from an object pointing at different files depending on whether doing a watch/package build, to a single binary file for both
2. updates the storybook build samples to storybook v9, I mostly did this to try and reproduce an issue at our work rush monorepo around storybook and watch mode, which turned out to be related to the heft-rspack-plugin instead
3. added support for detecting the --serve flag when using the heft-rspack-plugin via the same method as the webpack plugins

Details

3 is not done correctly, when adding a dependency on the heft-rspack-plugin to import the same types as the heft-webpack plugins I started getting the following typescript errors

ncountered 3 errors

I'm not really sure what is going on there, so I opted to just drop the dependency and work around the missing types. This was enough to generate a patch for our internal Rush monorepo which is what I am after.

How it was tested

Built the storybook sample project

Impacted documentation

I don't think so?
