(external): [update] Catalog Brands, update meta_keywords description…

…s and examples (#50)

While working through the API I noticed the description and examples for
meta_kaywords don't reflect what is received back from the actual
request. This hopefully should fix that.

- Sorry for accidentally deleting the last one.

# Update meta_keywords Descriptions and Examples


## What changed?
<!-- Provide a bulleted list in the present tense -->
* Changed description from "Comma-separated list of meta keywords to
include in the HTML." to "An array of meta keywords to include in the
HTML."
* Changed examples to be an array of keywords and not a comma-separated
string

## Release notes draft
Update Brand's V3 documentation to correctly represent what is returned
in the response.

     Our Catalog Brands endpoints let you [create individual brands](/docs/rest-catalog/brands#create-a-brand) and [modify the brands](/docs/rest-catalog/brands#update-a-brand) associated with a store's products, along with [deleting brands](/docs/rest-catalog/brands#delete-a-brand).

     Brand images have their own dedicated [create a brand image](/docs/rest-catalog/brands/images#create-a-brand-image) and [delete a brand image](/docs/rest-catalog/brands/images#delete-a-brand-image) endpoints.

     In addition, brands have metafields that you can use to store information structured in key-value pairs; learn more about [creating brand metafields](/docs/rest-catalog/brands/metafields#create-a-brand-metafield), [updating brand metafields](/docs/rest-catalog/brands/metafields#update-a-brand-metafield), and [deleting brand metafields](/docs/rest-catalog/brands/metafields#delete-a-brand-metafield).
