Describe capabilities in module page

Currently the information on the module page describing what the module can do is very limited. It reads:

"This simple module created to provide key site settings to the frontend via JSON:API. It also has an API hook to add some additional information to data. After enabling module, you can open /jsonapi/site/site URL and read data. You must use key_auth authentication provided by Key Auth module, to prevent unauthorized access."

Ideally it should also say:

• Which settings and info is made available via the API
• If it allows writing settings (in addition to reading)
• What the intended purpose of the module is. E.g. to fill in gaps in the standard Drupal API so that decoupled apps can fully manage a Drupal site.
