[MDeLuise]

Description

This PR enhances the descriptions for various properties used in job steps related to keystore management. The changes aim to provide clearer guidance for users, helping them retrieve the correct values for their use cases.

• Updated the description for the KEYSTORE_ID property in the "Key Store Certificate Create" and "Key Store Keypair Create" steps to clarify its purpose and retrieval method.
• Improved the descriptions for the KEYSTORE_ID and ALIAS properties in the "Key Store Item Delete" step to ensure users understand where to find these identifiers.

These improvements contribute to a better user experience by making the documentation more intuitive and accessible.
