[Serverless] Index Management page displays duplicate Docs links

[KOTungseth]

On the serverless Index Management page, we provide users with two links for the Index Management page in the docs:

• Index Management docs on the main page
• Learn more on the Indices tab

The Learn more link signifies that users can go to the Index Management docs to learn about updating their Elasticsearch indices individually or in bulk, but the docs do not include this information.

We should either:

• Update the Index Management docs to include how users can update their Elasticsearch indices individually or in bulk
• Remove the Learn more link
