v4 -> v5

Pollen v5 introduced several breaking changes to fix unintuitive behavior and lay stronger foundations for the future

Breaking changes

• The pollen-css library is now ESM-only, not CommonJS

• Dropped support for < Node v16

• CSS import moved to /pollen.css rather than default package export

• Properties keys in modules are no longer converted from camelCase to kebab-case when generating CSS variables

• Default color palette has been replaced with a much more robust and extensive palette, adapted from Tailwind's

• Deprecated modules elevation and easing removed, replaced by the new modules introduced in v4 (shadow and ease respectfully)

Migration Guide

1. If you're using the default CSS from Pollen, update your import path from pollen-css to pollen-css/pollen.css

2. Ensure you're using Node v16+

3. If you have your own config, update any camelCase property names to be kebeb-case

4. If you are using Pollen's default color palette, get the output from v4 (in JSON format for easier migration) and add it to custom config in v5, since the default palette has changed significantly

5. If you are still using the deprecated default modules --elevation or --easing update them to --shadow and --ease respevitvely
