documentation maintenance

There are some unclear parts in the documentation and also some bad code examples or misleading wording:

[x] Remove --open argument from the command and add a quote mentioning this argument to quickly open the app at https://react-server.dev/guide/get-started#development-mode
[x] "Next steps" section in the "Get Started" guide should be reworked to have a conclusion at the end while still encouraging the developer to dive into the details https://react-server.dev/guide/get-started#next-steps
[x] Add a guide page about how the framework works with Vite using this blogpost as a base https://dev.to/lazarv/migrating-a-vite-react-app-to-use-react-server-components-507j
[x] Add a guide page about using TypeScript with the framework with a suggested tsconfig.json
[x] Add a guide page about using Tailwind CSS with the framework with manual installation steps
[x] Fix code example at https://react-server.dev/router/markdown#plugins
[x] Fix code example at https://react-server.dev/router/markdown#custom-mdx-components
