contracts compilation fails on github action

[gaboesquivel]

I'm running into this issue when trying to compile a smart contract using eosio-cpp in the github action. It gets stuck 9/10 times during the compilation. It might be related to the issue that compilation needs at least 2 CPUs EOSIO/eosio.cdt#288 (comment)

A posible workaround would be to push the wasm and the abi to github so compilation on the action is not necessary. Or setup a service that you can call from the action in order to get wasm and abi, this would be a fine solution for public repos.

this seems to be working fine for nexus https://github.com/nexus-finance/eosio-contracts/blob/master/.github/workflows/compile.yml
