Expanding lambda effect examples

**Describe the problem you have/What new integration you would like**

So i have spent the last two evenings learning to use addressable lights within ESPHome
And when it comes to light effects, most examples can be copy pasted for a quick and easy test, or just to use those.
But for the Lambda effect, some people might be scared off, by the aspect of using another language when perhaps being new to
YAML as well.
So i'm suggesting an expansion into the docs for this specific effect, with a few examples one could actually copy/paste, see it work
and tweak some parameters. Essentially lowering the entry level.
I'll put some example of ideas for examples in the additional context bit.

**Please describe your use case for this integration and alternatives you've tried:**

I'm too stupid to learn two things at once.
