Bugfix : summary: undefined type issue

[angad-sethi]

Closes #27129

What I did

I've updated the type for ArgType.table.type.summary to be string | undefined so as to enable exactOptionalPropertyTypes: true in tsconfig.json

I've cloned your repository, how can I test this from a project using storybook ? I guess I need to replace the version used by the local repo I cloned, but I've never done that. Could you share some pointers ? :)

@Hyzual I have created a canary release. You can try it out by upgrading Storybook to it:

The TypeScript error is still present. We have found that we had to modify an interface named InputType from the @storybook/types package to add string | undefined for the TypeScript error to be fixed. I tried looking for it in the code but did not find it 😓. If you know where it is and could change it, I would be grateful!
