fix(docz-core): always use custom prop filter if it's provided (#1403)

Description

Closes #1403

I'm curious how y'all feel about considering this a "breaking change" vs just a "fix".

Technically the new behavior is different from the old behavior and folks who are using a custom propFilter might end up seeing more props after this is merged.

Here's a summary:

Old behavior (without a custom prop filter):

• any props that don't have a parent are included
• any props that have a non-node_module parent are included

New behavior (without a custom prop filter):

• same as old behavior

---

Old behavior (with custom prop filter):

• any props that don't have a parent are included
• any props that have a non-node_module parent are include
• any props that 1) have a parent and 2) parent is a node_module - will be run through the custom prop filter

This behavior seemed like a bug to me. The custom prop filter is almost always ignored and is only useful for white-listing some props that come from node_modules

New behavior (with custom prop filter):

• all props are run through the custom prop filter

So, if folks were actually relying on the old "buggy" behavior of propFilter just being a node_modules whitelist, they will need to add some logic to their propFilter in order to re-create the old behavior.

Overall I believe that this new API is the right API, and it's just a matter of how to approach the change with the community, which I'll leave up to the maintainers

CI is failing here:

/examples/typescript/src/components/Button.tsx
  53:3  error  Parsing error: Unexpected token

  51 | export interface ButtonProps {
  52 |   scale: 'small' | 'normal' | 'big'
> 53 |   kind: 'primary' | 'secondary' | 'cancel' | 'dark' | 'gray'
     |   ^
  54 |   outline: boolean
  55 | }
  56 | 

This doesn't seem like it's related to my change.

I saw this error during development as well. Curiously, adding semi-colons fixes the issue, but I wouldn't expect that they're needed.

Can you rebase from master, I've fixed the CI issue

Looks good now 👍
