cmd/git(fix[show]): Fix incorrect boolean condition for no_query_remotes

why: The condition `if no_query_remotes is not None or no_query_remotes:`
incorrectly adds the -n flag when no_query_remotes=False, because
`False is not None` evaluates to True.
what:
- Change condition to `if no_query_remotes:` in GitRemoteCmd.show()
- Change condition to `if no_query_remotes:` in GitRemoteManager.show()
