Publish filecoin-solidity package to soldeer

[jimpick]

Foundry has a new method of managing libraries that is an improvement over git submodules:

https://book.getfoundry.sh/projects/soldeer

I can install filecoin-solidity to foundry using soldeer via:

forge soldeer install @filecoin-solidity~1.1.2 --url https://github.com/filecoin-project/filecoin-solidity/archive/refs/tags/v1.1.2.zip

It would be super nice and aid discovery if the package was published to the soldeer repo:
