Generate config documentation from application.properties

[nscuro]

Description

Generates config documentation from application.properties.

Leverages the GenerateConfigDocs JBang script (https://github.com/DependencyTrack/jbang-catalog/blob/main/GenerateConfigDocs.java) to generate reference documentation from the application.properties file.

This makes application.properties the single source of truth for configuration options. We no longer need to copy-paste its contents to multiple places for documentation purposes.

The documentation is re-generated automatically whenever application.properties changes.

This is already done for the Hyades project (https://github.com/DependencyTrack/hyades/blob/2f95363fbf51423876a8eb2c7f0bc55a53ba85f9/DEVELOPING.md?plain=1#L11-L61) and turned out to be useful, so backporting it here.
