Align project namespace and file names

Problem/Motivation

After downloading the module, you automatically assume that you can install it using the same namespace, as you can everywhere else.

But you get an error:

$ composer require drupal/chatgpt_plugin
$ drush in chatgpt_plugin
In PmCommands.php line 333:
Unable to install modules chatgpt_plugin due to missing modules chatgpt_plugin

Ideally, the namespace (project URL) and file names should be aligned. The project namespace is chatgpt_plugin (https://www.drupal.org/project/chatgpt_plugin) but file names are chatgpt.info.yml ...

These files should probably be called chatgpt_plugin.info.yml, chatgpt_plugin.module, etc. instead.

This way people can download and install using the same namespace, without getting an error.
