Docs: add dynamic params to AvatarComponent

As a PoC I've added dynamic params to AvatarComponent. Now it's possible to change them on the fly

According to the #180

Here you can see how it looks like:

It works great! The only thing I noticed is that params not included in source won't make any impact on preview (eg Size in Default preview). Maybe it will be better to have a showcase of all possible params in "Default" preview? And in other previews allow to change only params that are included in source?

We could also add "Basic" preview and use it to show the most simple usage example (that's what our current "Default" preview does). What do you think?

Yep, my bad. Forgot to pass size param to component

I like the idea of changing only source params, I think it will be more straightforward and easier to understand for users.

Agree, added all available params to the Default preview and created a Basic preview
