Add an option to hide deprecated parameters in Redoc

As an API documentation user and developer, I would like to have the ability to hide deprecated parameters in the Redoc-rendered documentation. This feature would provide an additional level of control over the display of deprecated parameters, making it easier for API consumers to focus on the most relevant and up-to-date parts of the API.

Proposed Solution:

Introduce a new configuration option, such as hideDeprecatedParameters, that controls the visibility of deprecated parameters in the Redoc-rendered documentation. This option could be set to true or false, with the default value being false to maintain backward compatibility.

hideDeprecatedParameters: true

This feature request aligns with Redoc's goal of providing a customizable and user-friendly API documentation experience. Implementing the ability to hide deprecated parameters would be a valuable addition to Redoc's already robust feature set, further enhancing its utility for both API consumers and developers.

Start by locating Redoc's configuration-option handling and the rendering path for API parameters, then inspect how deprecated parameters are currently displayed. Add the proposed hideDeprecatedParameters option with a default of false, and verify that true hides deprecated parameters while false preserves existing output.
