expand description of swagger /auth/query to add retrieve information

Describe the bug
A clear and concise description of what the bug is.

I think I have done a certificate sign-on - but would like to display the userid which was activated. I could not find a REST request for this.

I found /auth/query
Validate the authentication token. - but I did not want to validate - I wanted to display...

After half an hour, and google, I found

https://petstore.swagger.io/?url=https://raw.githubusercontent.com/zowe/docs-site/docs-staging/api_definitions/gateway.json#/Security/validateUsingGET

which says

Use the /query API to validate the token and retrieve the information associated with the token.

Please can you change the swagger definitions
from
Validate the authentication token.
to
Validate the token and retrieve the information associated with the token

Start with the linked Swagger definition and locate the /auth/query endpoint description in the API-layer documentation source. Change the summary so it says the endpoint validates the token and retrieves the information associated with it, then verify the rendered Swagger documentation shows the updated wording.
