fix(storybook): expose Inter local fonts to storybook

[TylerAPfledderer]

Description

Somehow in a past build (probably during the project migration to NextJS), the Inter font lost exposure in Storybook; It is no longer available in the existing configuration to being available to the Chakra theme in the SB environment.

And with the Inter font now being served locally via PR #12501, there needed to be different approach to applying it back into the environment

• Creates preview-head.html to redefine the CSS variable --font-inter to it is available to the Chakra theme in the SB environment
  • This variable in prod is currently declared in _app.tsx so it is unavailable to the SB environment from that location
• Exposes the global.css to make the inter font faces available

Additional Information

This PR does not consider the mono font, which is also not exposed to Storybook. Because of the current approach to making the font available for Chakra in NextJS, it makes it difficult to apply in SB. Recommend also adding this font locally.
