Add Tags (and Release) for each version

[cderv]

Currently tags and release stopped at version 0.9 https://github.com/rte-antares-rpackage/antaresXpansion/tags https://github.com/rte-antares-rpackage/antaresXpansion/releases

Last version is 0.13

The tags are useful to get stable version quickly even is not deployed in a CRAN repo. This would be required too for internal deployement.

I don't think I have the right to do myself.
