Docs: Review and integrate new official documentation

### Description

I have created an initial draft for the `array_record` documentation, which is now hosted on ReadTheDocs:

**[https://array-record.readthedocs.io/en/latest/](https://array-record.readthedocs.io/en/latest/)**

This issue is to track the process of reviewing, revising, and formally adopting this as the official documentation for the project.

### Tasks

* [ ] Review the current draft for accuracy, clarity, and completeness.
* [ ] Identify any missing sections or topics that need to be added.
* [ ] Discuss and implement necessary revisions based on feedback.
* [ ] Formally integrate the documentation (e.g., link from the README, set up CI/CD for doc builds if needed).
