Missing the license header for GPL-3.0

Expected behavior

👋 Per SPDX license index, gpl-3.0 is the deprecated license, adding a license header would further clarify the license application and solve my issue. Thanks.

Kind of relates to https://github.com/Homebrew/homebrew-core/pull/59739

Cheers.

Possible action

Including this into the README (for gpl-3.0-or-later):

I don't think this is a bug. This is merely a convince. The LICENSE file clearly states it is 3.0 and not 3.0 or later. Also 3.0 is not deprecated but SPDX wants you to clarify if it is 3.0-only or 3.0-or-later.

Homebrew could also just parse the LICENSE file or ask the GitHub Api.
