Subject: [PATCH] fix: Explicitly allow undefined type for table.type.summary

Closes storybookjs/storybook#27129

Allowing explicitly undefined as type for table.type.summary lets Story
authors disable the automatic type summary while having strict
TypeScript options. With exactOptionalPropertyTypes enforced, using
undefined as a type was forbidden, as TypeScript would raise an error.
With this change, it should be allowed.
