PPDSC-2481

1. Background - why this is needed

• Users want to see Storybook components in their own themes

2. What did you do

• Added MArketwatch at WSJ themes to Storybook

3. What does the reviewers should expect

• Able to select MW and WSJ themes in toolbar dropdown

I have done:

• Written unit tests against changes
• Written functional tests against the component and/or NewsKit site
• Updated relevant documentation

I have tested manually:

• The feature's functionality is working as expected on Chrome, Firefox, Safari and Edge
• The screen reader reads and flows through the elements as expected.
• There are no new errors in the browser console coming from this PR.
• When visual test is not added, it renders correctly on different browsers and mobile viewports (Safari, Firefox, small mobile viewport, tablet)
• The Playground feature is working as expected

We should get rid of woff files, they just make noise, all modern browsers support woff2

[mstuartf]

Done.

For the one you just removed, do you need to also update the @font-face? I think some are still looking for woff file even now we are not downloading it anymore!

I would maybe then just double check everything still looks good, but should be ok

[mstuartf]

Done.
