[Documentation] Difficulty in Creating Basic Content Type Filters

[MikeKry]

Problem Description:

It has come to my attention that several developers face challenges when attempting to create basic content type filters. This recurring issue suggests that there might be a gap in our documentation that leaves developers without clear guidance on this relatively straightforward task.

Mostly it was about developers not knowing about this possibility, failure the importance of using WhereInputQueryObjectType or need to register IIndexAliasProvider.

Proposed Solution:

To improve developer experience and address this problem, I propose we enhance our documentation. Specifically, I have drafted additional documentation focusing on guiding developers through the process of creating these filters step by step.

Call to Action:

I have submitted a pull request with the proposed documentation changes here: #16111

I welcome feedback on the PR and am open to suggestions on further improving the documentation to make this process as clear as possible for all our developers.
