"GPL-3.0-or-later" is not accepted as a valid license

[progval]

I get this when running cargo publish:

error: api errors: unknown license or other term: GPL-3.0-or-later; see http://opensource.org/licenses for options, and http://spdx.org/licenses/ for their identifiers

But "GPL-3.0-or-later" is listed here: https://spdx.org/licenses/

Created an upstream issue, ehuss/license-exprs#27

Closing this, since it's an upstream issue
