Modernize CI workflow

This PR uses the same workflow we have been using in other projects under pytest-dev:

* Separete `test` and `deploy` workflows.
* `test`: build package once and test it in the supported environments, as opposed to generate one package for each environment.
* `deploy`: a manually triggered action, which once successful will tag the repository and create a GH release.
