feat: update structure

[itsacoyote]

Description

• Update @nuxt/eslint to 0.5.3 to fix some eslint flat config errors. Restart your ESLint Server via VSCode panel or VSCode itself to get eslint working again.
• Add a "category" for paths to help group content for algolia search.
• Update the DOM for the page layout to help with algolia search crawling.
• Major readjustment to the pages to improve paths. Folders should have a index.md so that URLs that go to a folder path like /js/ethers/api have a page to default to for the API folder. Primarily for SEO, linking, and breadcrumbs.

The main thing to review is the page layout component: https://github.com/zksync-sdk/sdk-docs/compare/update-structure?expand=1#diff-575d0b4cf7e94b73d7e421f4482180f1832f172bfef28701cf37a48f51d2a17d and the useCategory composable: https://github.com/zksync-sdk/sdk-docs/compare/update-structure?expand=1#diff-289f43ba82dae8afff0e3bd22ebfe1fb5c982ed37b483c2918cc1a8071930cbb
