Rm unnecessary warning msg "Failed to read git credential file" (#1479)

* Rm unnecessary warning msg "Failed to read git credential file"

Fixed #1476

If `gh auth token` executed successfully and binstall obtained a gh
token from it, then there's no reason to issue any warning msg.

Only when binstall cannot read from `.git-credential` and
`gh auth token` failed does binstall need to issue warning.
