Style attributes not updating with state

[ngarnsworthy]

Hi! 👋

Firstly, thanks for your work on this project! 🙂

Today I used patch-package to patch react-leaflet@5.0.0 for the project I'm working on.

I found that when I was updating the color prop for Polygons and Polylines the component did not update the underlying Leaflet object. I found the update function was only checking for changes to the positions. I made a quick fix to this but a implementation would have to fix the object comparison not working properly.

Here is the diff that solved my problem:
