Have a way to define display name for prompt/tool/resource input so that the UI looks nicer.

For example, it is not very nice to display parameters like this, it's especially worse if the parameter is in camelCase.

Describe the solution you'd like

Have a way to define display name for prompt so that clients can use to render better UI/UX. It should be JSON schema and Zod schema compatible to make it easy for developers to define.
