Feature description

act complains when there's no remote repo.

Sometimes, a dev just wants to test ideas locally before creating a remote repo. :)

Line 172 in ccd28e7

common.Logger(ctx).Warningf("unable to get git repo (githubInstance: %v; remoteName: %v, repoPath: %v): %v", githubInstance, remoteName, repoPath, err)

func (ghc *GithubContext) SetRepositoryAndOwner(ctx context.Context, githubInstance string, remoteName string, repoPath string) {
	if ghc.Repository == "" {

		if err != nil {

The main issue is getGithubContext is called in multiple places, so the error repeats over and over.
