Add language direction picker to Storybook

Fixes #332 by @sarayourfriend

Description

Adds a language direction picker in Storybook to make it easier to test RTL styles.

Note: TailwindCSS RTL still isn't installed in this branch but this PR will introduce it. This PR does not introduce any RTL styles, just the ability to easily change the dir attribute on the storybook iframe and updating the locale properties dir attribute that would be used to programatically detect language direction in the app.

Testing Instructions

Checkout this branch and run npm run storybook. Then navigate to any story (like http://localhost:6006/?path=/story/components-downloadbutton--default) and click on the globe icon in the toolbar for the story. Select RTL and ensure that the dir attribute is set on the storybook iframe and that the component is indeed rendered in reverse.

Again, there are currently no RTL styles being applied so the component will be broken in RTL mode. This is expected.

The DownloadButton has been converted to use tailwindcss-rtl classes so you should be able to test against that.

This addition will greatly help us improve RTL styling.
Amazing magic with Storybook hooks, Nuxt, Vue, Composition API, React and whatever else needed to be used here!

I'm not sure but potentially this PR should wait for after the Nuxt Bridge upgrade?

[sarayourfriend]

I've rebased this PR onto the lastest main branch which has tailwindcss-rtl installed. You should now be able to test this against the DownloadButton and confirm that it looks good in both LTR and RTL modes 🙂

Works great!
