Add a way to put links into the confapp

### Motivation

There's sometimes useful information worth adding to the confapp for components, for example:
- A link to a generated example schematic
- A link to the original Dart/ROHD source code for the component
- The component documentation in ROHD-HCL
- Additional details/documentation/information

### Desired solution

Add a way to add links that would appear in the confapp in `Configurator`. Perhaps make certain links mandatory for all ROHD-HCL components?
