cmd/git(fix[run]): Remove invalid cached parameter from branch and stash

why: The cached parameter appended --cached to git branch and git stash
commands, but neither command supports this option. Any caller using
cached=True would get a CLI error.
what:
- Remove cached parameter from GitBranchCmd.run()
- Remove cached parameter from GitBranchManager.run()
- Remove cached parameter from GitStashCmd.run()
