Add a cron schedule in actions per month to create artifacts

Thank you @Mariosmsk

The reasoning for this commit is that the Artifacts' retention policy is 90 days at most so the compiled DLLs are gone if we don't push anything within this period.

Just asking because I'm curious - why does anyone need to access the artifacts?

[eladsal]

@samhatchett, the artifacts are the compiled DLLs for the different environments. This is the only place people can access them without compiling the code, and they are updated for every commit.

@eladsal thanks, i see. why not use Releases for that access?

[eladsal]

At least back then releases were not compiling automatically the DLLs with every push.
