[Feature Request]: Accept --configFolderPath option in automigrators & migrators

[mandarini]

Is your feature request related to a problem? Please describe

We want to be able to call the automigrators from Nx. In Nx, there are multiple .storybook directories, and multiple .storybook/main|preview.js files.

From within a Nx generator, we want to recursively call the automigrators (eg. npx sb automigrate mainjsFramework) and also pass a flag to tell Storybook which directory to look into, so for example:

npx sb automigrate --fixId mainjsFramework -c apps/my-app/.storybook

That would enable us to call the automigrators from Nx, or allow anyone to call the automigrators for a Nx workspace.

Describe the solution you'd like

The functions that are listed here to accept an option for configFolderPath (or anything similarly named, to allow Nx to pass the directory).

Similarly, if there's a migrator that looks for any other Storybook-related files (eg. stories transformation) to accept a relevant glob or something (like sb migrate csf-2-to-3 which accepts --glob).
