Colored output is the default since hspec 2.9.5.
This causes CI failures due to terminal escaping characters when running
the doctests on GitHub Actions.
* bumped cabal-version field
Cabal supports two types of licenses, native and SPDX, which can be seen here hackage.haskell.org/package/Cabal-3.6.2.0/docs/Distribution-Types-PackageDescription.html#v:licenseRaw
Several packages use BSD-3-Clause as a license, in conjonction with cabal-version: >=1.10 which cabal parses as Right (UnknownLicense "BSD-3").
If I change teh cabal-version to cabal-version: 2.2 , cabal correctly identifdies the license License (ELicense (ELicenseId BSD_3_Clause)).
* changed license from cabal to spdx format
aka BSD3 -> BSD-3-Clause: next cabal may deprecate the old format
