Interactivity API: Improve readability in directives check function inside vdom.ts

[cbravobernal]

          This section could probably use some comments about how strings are being split up and what we expect to find in each part. We've even got a constant `wp` that's the `directivePrefix` (that also appears in the middle of the data attribute).

Honestly, some kind of description of what the parts of a directive are and a refactor to rename things accordingly would be helpful. prefix and suffix don't really make sense:

nothing?       suffix is everything after `prefix--`… I guess this makes sense
   |              |
vvvvvvv       vvvvvvvvvv   
data-wp-bind--on--change
        ^^^^
          |
      "prefix" in the middle?

Maybe we could talk about these things like the "directive name" or "directive type", then the rest of it could be some kind of input to the directive? I think we use these prefix/suffix names across the package and it seems confusing.

The bug fix here where we try to access a null match is good 👍

Thanks for contributing!

I left some feedback, but I would love more input for other folks.

Naming variables is a tough task! 😅

Finally I decided we are not going to go with this issue/PR.
The terms prefix and suffix appears through all Interactivity codebase , and is not something we can change slightly.
