Alois Klink b4164b6ab5 test: test that styles and themes return valid CSS ...

Test that `src/diagrams/*/styles.ts` module returns a valid
CSS stylesheet that can be parsed via [stylis][1] and then
becomes a valid CSS that [csstree-validator][2] validates.

We test this for every diagram and for every theme, because
many of the invalid CSS bugs are caused by missing theme vars.

There are some CSS errors that I couldn't easily fix, so I've written
the tests to ignore the following CSS errors:
  - 'Unknown property `rx`' (Valid in SVG2 draft and in some browsers)
  - 'Unknown property `ry`' (Valid in SVG2 draft and in some browsers)
  - 'Unknown property `dy`'
    - This doesn't seem to be valid CSS in any SVG version, but maybe
      some browsers support it 🤷 I feel like we should probably change
      this though.
