Canonical version numbering and release notes

[PeterTYLiu]

There doesn't seem to be a central log of release notes or verison number for radix icons, and what info does exist across various sources is wildly inconsistent.

As of this writing:

1.3.0 in https://github.com/radix-ui/icons/blob/master/packages/radix-icons/package.json

1.0.3 in https://github.com/radix-ui/icons/tree/master

4.0.0 on https://www.npmjs.com/package/@modulz/radix-icons
