I know that chrome extensions use 'manifest.json`, but here, it is used as something else as well.

When I change some value, page update, but nothing changes.
It's a Web App Manifest that describes your application and it's used by e.g. mobile phones if a shortcut is added to the homescreen.
From MDN (linked above):
The web app manifest provides information about an application (such as name, author, icon, and description) in a JSON text file. The purpose of the manifest is to install web applications to the homescreen of a device, providing users with quicker access and a richer experience.
manifest.json is the json file that is mostly used to describe our app on mobile phones.
The manifest.json provides information about a web application in a JSON text file, necessary for the web app to be downloaded and be presented to the user similarly to a native app (e.g., be installed on the homescreen of a device, providing users with quicker access and a richer experience). PWA manifests include its name, author, icon(s), version, description, and list of all the necessary resources (among other things).
