chore: post-rename cleanup + libevm intro (#68)

## Why this should be merged

Cleans up loose ends after renaming the Go module. Also adds an
introduction to the README to explain the purpose of libevm.

## How this works

The changed hash in the workflow is just a fix (although a no-op). The
spaces after the copyright headers are to stop them from [showing up in
documentation](https://pkg.go.dev/github.com/ava-labs/libevm@v1.13.14-0.1.0-rc.1/params).

## How this was tested

+The Ethereum Virtual Machine (EVM) as a library, `libevm` is a fork of [`geth`](https://github.com/ethereum/go-ethereum) with
+injectable configuration directives. Although designed to support the Avalanche [C-Chain](https://github.com/ava-labs/coreth) and
+[EVM-L1s](https://github.com/ava-labs/subnet-evm) (formerly _subnets_), configuration is general-purpose and backwards-compatible
+with `geth`.
+
+
+We are immensely grateful for the hard work of the `geth` authors, and hope that our contribution can be of value to others too. Thank you!
