feat(deployment): Added Classname to ExposeDeploymentViaIngressOptions

[yashisrani]

Fixes #2178

Description

• Enhance the exposeViaIngress("/") method by allowing the className option to be set directly.
• This will improve consistency between constructors and exposeXXX methods while making the code more concise and meaningful.

Proposed Solution

• Modify the exposeViaIngress() method to accept a className option:

deployment.exposeViaIngress("/", { className: "nginx" });
