ReadBranchConfig parses the `branch.BRANCH.(remote|merge|pushremote|gh-merge-base)` part of git config. If no branch config is found or there is an error in the command, it returns an empty BranchConfig. Downstream consumers of ReadBranchConfig should consider the behavior they desire if this errors
