Here is the official description: GATT Descriptors | Bluetooth Technology Website
Basically, they describe the characteristic they are attached to.
So, it's like the comments for a function, but is useful for allowing a remote device to read and display to the user for explaining the usage/functionality of a characteristic.
Note: The Client Characteristic Configuration Descriptor is a specific attribute used to enable/disable indications, notifications, etc. for the associated attribute and shouldn't be confused with the simple "descriptor" that just holds metadata about the characteristic as defined by your application/service/device.
