fix(node-plop): Correct types

[xeho91]

Hi, I love using your package to improve my workflows. Thanks for it!

While coding something new, I found a few typing issues, so I thought of immediately fixing them.

According to the code from these lines:

• https://github.com/plopjs/plop/blob/973c1ce566db6fc754af55672b47ae4ed80ae4d0/packages/node-plop/src/actions/append.js#L32
• https://github.com/plopjs/plop/blob/973c1ce566db6fc754af55672b47ae4ed80ae4d0/packages/node-plop/src/actions/modify.js#L30

both action types - "append" and "modify" - accept pattern property in options (cfg) optionally.

---

Another one is the incorrectly inherited property path inside AddManyActionConfig from AddActionCOnfig. I've confirmed there, that it is actually not being used at all.
