Europa docs: From local dev to CI environment doc page

The todoapp example contains a Netlify plan which uses the latest dagger
additions: do & Client API. We are thinking of merging the examples
repository into this one to make working with this easier. This is a
step in that direction.

We are not using the yarn package so that we can revert
https://github.com/dagger/dagger/pull/1673 without breaking this
implementation.

The GitHub Action is WIP, we will continue with that tomorrow:
https://github.com/dagger/dagger-for-github/issues/24
