* feat(storybook): Refactor Storybook to use Typescript

This commit updates the Storybook configuration to use Typescript, including renaming `main.js` to `main.ts`, updating `core.builder` and `framework.name` to use `@storybook/builder-webpack5` and `@storybook/react-webpack5`, respectively. The code also adds options to `addon-docs` to enable adding GFM support to the generated docs. Additionally, the commit modifies `staticDir`, removes outdated addons, and makes various devDependencies and PostCSS updates to align with Storybook 7.x.x. Finally, the commit removes some unused code and relocates `Button` and `AboutModal` story files.
