Update examples to use standalone

[timdeschryver]

With standalone become more mainstream and the default, I think we should update most of the examples.
We can leave one example to use NgModule.

I can help with the migration, but I wanted to verify if this is OK.

I'm in the middle of refactoring a codebase to standalone. Currently stuck on this step so I'd appreciate an example.
Found an example in the docs. Did it for me.

That is totally fine. I wanted to migrate this lib to nx. Should we do this before or after? What do you think? @timdeschryver ?

@FabianGosebrink it doesn't matter I think, both are fine.
I wanted to start on this, but some things got in between 😅

Would love to merge first. Will start next week maybe.
