infra: our licenses.html file is not deterministically generated

[abernix]

It would seem that the cargo about generate --workspace -o licenses.html about.hbs file generates different results (potentially based on different operating systems? glibc versions? Something else? Not sure.)

This results in our CI job which enforces compliance failing sporadically and succeeding on a "Re-run from Failed" invocation.

This will likely need to be fixed upstream, and @o0Ignition0o has opened EmbarkStudios/cargo-about#202 as a basis for collaboration, but this tracks that on our own repository as an infra chore.

I believe a good first step would be to display the diff when the CI run fails.

#1524 adresses my comment above.
