docs: fix custom_attributes example in company response across all spec versions (#470)

Replace `creation_source: api` with `industry: manufacturing` in the
Create/Update Company response example. `creation_source` is a system-managed
field, not a custom attribute — the new example better illustrates user-defined
custom attributes. Also removes a trailing space in v2.7.
