Move example to examples directory and add additional examples

[KyleJune]

This will help with ensuring that changes don't break any of the examples that I currently have in separate repositories. It will also make it easier to show how a PR impacts examples and users can update their code if there are breaking changes in the future.

The separate example repositories will have the same code, except the import map in the deno.jsonc will point to the latest published version instead of the current code. They will exist so that it will be easy for users to clone the examples with their github actions included.
