Bump to latest Ethers (#26)

* chore: bump ethers

* fix: adjust ethers breaking changes

1. Use the abigen'd ::deploy methods
2. Use Anvil instead of Ganache

* silence warning

* fix: replace abi with full verifier artifact

* ci: use anvil instead of the node stack

* chore: remove ethers-solc

* fix: return error instead of raise

17c0834abf
this api got deprecated and would panic instead of generating an error that can behandled

* lints

* minimfy json
