The DATABASE_URL variable in the .env file examples was missing an equal sign, preventing it from parsing correctly. This fix ensures the environment variable is properly loaded and available during application runtime.
`npm run install` in the first place is not a valid command, `yarn run install` will also be fixed by this change as we are using **npm-to-yarn** package for its conversion (tested).
`yarn run start` is a valid command, i know `yarn start` is a **short-hand** but i cant help here as we have't hardcoded it in the docs its being converted through the same package mentioned above, anyways both are valid so should be fine ig.
- Add a new homepage to `book` project for the routing page
- Move all main doc pages to be under `/v2/learn` (and added redirects + fixed links across docs)
- Other: add admin components to resources dropdown + fixes to search on mobile.
