Fix: signature of tar balls

Uses the `sign-release`files` action instead of using curl manually.

This allows us easier maintenance as we can get support from a dedicated
team.

Besides that the version calculation is separated into an own job by
using the output functionality. This allows us to reuse that calculation
later.
