@addon/docs: Angular numeric property with default value 0 is undefined and can't be changed

[stefan-schweiger]

Describe the bug
If you have a numeric input with the default value 0 @Input() value = 0 and use compodoc to generate your docs the value is set to undefined and you can't change it anymore.

I already have a fix for this and I'm going to make a PR right after filing this issue. It just adds this addtional check in extractTypeFromValue in the file compodoc.ts.

// current main
return defaultValue || valueType === 'boolean' || valueType === 'string' ? valueType : null;
// my PR
return defaultValue || valueType === 'number' || valueType === 'boolean' || valueType === 'string' ? valueType : null;

To Reproduce
Just add @Input() value = 0 to the doc-button in the example angular project.
