Generate source for story Meta in csf-tools

[JonahPlusPlus]

Is your feature request related to a problem? Please describe.

I'm updating storybook-solidjs to have support for code snippets generation. SolidJS does not have a VDOM to get info from, so I've opted to use the source code from csf-tools, and run a JSX parser and extract arguments from the AST. So far, this is going well.

The problem is getting the component name. For now, I've opted to extract it from the title, but this isn't necessarily correct. I've noticed that csf-tools generates a description for both the meta and the story, but only generates a source for the story. If it were to generate a source for the meta, I would be able to use the component field to get the proper name.

Describe the solution you'd like

First, change enrichCsfMeta to extract the meta's source and add it to the parameters.

Alos, remove the current parameters.docs.source field (which I'll call a SourceObj type) in StoryContext.
Replace it with a source field where contents are of the form:

{
  component: SourceObj,
  story: SourceObj,
}

to reflect the current parameters.docs.description field.

Describe alternatives you've considered

Alternatively, if this breaking change (changing the shape of source) is a concern, add to the SourceObj type fields prefixed component*, to mark fields dedicated to the meta source.

Are you able to assist to bring the feature to reality?

yes, I can
