[hooks] [code_assets] README.md

[dcharkes]

This revamps the READMEs to include

1. code snippets with links to the examples, and
2. links to https://dart.dev/tools/hooks.

Side note, I'm thinking we might want to completely remove the examples from package:hooks and simply link to the examples in package:code_assets. The examples in package:hooks are rather artificial and more of a feature showcase, which makes them less understandable.

I think it is a good idea to link to the code_asset examples from the hooks readme, as you have done in this PR. I would keep the examples in the source tree, though. They are still useful to demonstrate individual features. I would add a link from hooks/examples/README.md to the more comprehensive examples in code_assets, though.
