Updated the curl method from POST to DELETE for deleting client secrets with UUID, in implementation.md

Description

Related Issue

https://github.com/AdobeDocs/adobe-dev-console/issues/90

Motivation and Context

The documentation on OAuth Server-to-Server credential implementation guide has wrong curl syntax ('POST' instead of 'DELETE') for deleting existing client secret using UUID. This fix would update the documentation to be more accurate.

How Has This Been Tested?

Tested the DELETE endpoint via POSTMAN on personal project.
