Provide a Github action/workflow to automatically manala up on .manala changes

[ogizanagi]

So we won't even miss an update

[nervo]

Wow, with a ready-to-merge pull request ?

With goreleaser, we could build a docker image, but before your issue, i've never seen a good reason to do it :)

Very basically introduced on-per-project basis with the following patch:

We could provide an official action for Manala setup and add a way to generate the worflow automatically with the Manala CLI.

what about having a .manala/github/workflow/update.yaml available through the recipe ?

[ogizanagi]

Sure, but the resulting path where to generate the workflow file has to be in the .github/workflow directory, so out of the .manala dir. I don't think there is any alternative available today.
