fix: pass config object to devCommand step handler

🎉 Thanks for submitting a pull request! 🎉

Summary

Fixes WRFL-2278

When plugins overrides the ENV via writing into args[0].netlifyConfig.build.environment, this new value is being applied to the environment.

But later on, the netlify cli, when it starts the dev server, it never passes this changed env var into it

Here is the dev Command
https://github.com/netlify/cli/blob/main/src/utils/run-build.ts#L90
startFrameworkServer passes settings, which has env but it's typically empty.

So, if I'm having a plugin which does change the env, it is never got into the user app.

To fix this, I'm just providing the arguments into the devCommand call, so then the place-of-usage (in this case - netlify-cli) can use it like that:

const devCommand = async ({ netlifyConfig }: { netlifyConfig: NetlifyConfig }) => {
  const env = {
      ...settings.env,
      ...netlifyConfig?.build.environment // now have access to this!
  };
}
