EVM link in index.html doesn't work properly

[ctharvey]

Causes example to fail if git is cloned. Resolved by replacing:

<script type="text/javascript" src="https://unpkg.com/evm-chains/lib/index.js"></script>

with

<script type="text/javascript" src="https://unpkg.com/evm-chains@0.2.0/dist/umd/index.min.js"></script>

Thanks for pointing it out! 🙌 Fixed on commit 97fc921
