Update creating a REST API doc

[DinithiDiaz]

Description

Created this issue to track the changes for creating a REST API feature for the MI VS Code extension.

Page to be updated: https://mi.docs.wso2.com/en/4.3.0/develop/creating-artifacts/creating-an-api/

Related Product issue/issues:

• Metadata files not getting created mi-vscode#70
• No option to import API from API Manager mi-vscode#71
• Add support for Service Catalog mi-vscode#61

The updating metadata section has been removed temporarily. Update the content once this feature is implemented properly.

This feature is not implemented yet in VSCode plugin. Hence adding the Future milestone. Once the feature is completed, the developer can update the docs accordingly.

Since we can derive the metadata need for the service catalog, we have improved the CAR plugin to generate them during project building via wso2/maven-tools#135. Hence we don't need to have this updating metadata section anymore.

We have updated the Integration first approach via https://mi.docs.wso2.com/en/latest/learn/integration-tutorials/service-catalog-tutorial/. Once the API first approach is implemented in MI VSCode plugin we can fix wso2/mi-vscode#71

As the VS code plugin capabilities are not available yet, resolving this issue.
