Workflow improvements #578
Description
There are a few pain points in the current workflow:
- Every time when we change devnet (e.g. when bumping RPC) and workflow fails (simply by failing tests) devnet isn't cached, so it rebuilds on new push. We should either download devnet release (much faster approach, downside is that we then can't use specific SHA) or cache devnet on workflow failure
- Some steps should be split into separate jobs, e.g. linting errors result in whole workflow failure, when in reality it should be just a separate job
