feat: now code examples are joined into one (#8284)

Joined all examples into one copyable example.

Did not do following ones, because they are using templates and probably
will not work as joined.

1. React
2. Svelte
3. Vue

Also skipped, because those examples are not final yet.

1. .NET
2. Android
