This PR fixes a build error for the Python package ward which I was encountering on nixos-unstable. Part of the build error message is included below for refrence:

error: builder for '/nix/store/sp03is988s3jj6kmalp20c6ssmamcdmy-python3.11-ward-0.68.0b0.drv' failed with exit code 1;

       >   - rich<13.0.0,>=12.2.0 not satisfied by version 13.7.1

I think there are two issues which this PR seeks to address:

• The hash for version 0.68.0b0 of ward did not seem to be correctly specified and was loading in an older version of ward. I have updated the hash - this fixes the rich version constraint .
• The version of cucumber-tag-expressions in nixpkgs unstable seems to be too up-to-date for the requirements of ward. I downgrade this to the version required by ward. Not sure if this is the best solution.

We can't override version for modules. if possible the constraint of cucumber-tag-expressions could be relaxed.

Otherwise we have to wait for upstream: darrenburns/ward#380

Understood, thanks for opening an issue upstream! Could I try changing the version constraints in the derivation?
