Allow deep-linking

[FloEdelmann]

Deep-linking to a page (e.g. https://docs.nestjs.com/v10/migration-guide) redirects to the homepage (of the current version 11). This makes the docs hard to use:

• search engine results doesn't lead to the result page directly
• sharing deep-links is useless
• reloading a tab or browser window loses the relevant content
