Work on clarification for LVAddons documentation

[svelderrainruiz]

That's a great start @svelderrainruiz, thanks a lot for doing that!
I'm also particularly interested in the PPL section when it's available.
Everything else seems pretty clear except for the "Per-target LibraryPaths" in the "Location of LVAddons" section, which I don't understand how to use. An example would be helpful.
As a more general comment, examples are likely appreciated everywhere for everything that can be set or customized, so there might be something to improve there IMO.
Another note, regarding the "SupportedBitness" JSON attribute. The documentation doesn't say if it is a String or Numeric datatype. Again, an example would clarify this.
Thank you so much!
