cmd/git(fix[run methods]): Forward **kwargs to underlying cmd.run calls

why: Multiple run() methods accepted **kwargs in their signatures but
did not forward them to self.cmd.run(), silently ignoring any extra
parameters like env, cwd, or custom config.
what:
- Add **kwargs to GitNotesManager.run() call
- Add **kwargs to GitBranchCmd.run() call
- Add **kwargs to GitBranchManager.run() call
- Add **kwargs to GitRemoteCmd.run() call
- Add **kwargs to GitRemoteManager.run() call
